Usage:
spyglass -verilog <options> <Verilog source file names>
spyglass -vhdl <options> <VHDL source file names>
spyglass -mixed <options> <Verilog and VHDL source file names>
spyglass -def <options> <Def source file names>
enable SpyGlass Rule-checking on specified
Verilog or VHDL source files, as per other
selected options.
spyglass -32bit run SpyGlass in 32bit mode. If the default startup
mode has been set as 64bit mode through the
configuration file, then this option can override
it and run SpyGlass in 64bit mode.
spyglass -64bit enforce 64bit binary execution on Linux(64-bit)
and Solaris(64-bit) machines (32-bit binary is
executed by default).
spyglass -version show SpyGlass version.
spyglass -usage show the standard option set.
spyglass -h | -help show site-specific help.
spyglass -quickstart show the `quick start' help.
spyglass -printrules [-verilog | -vhdl | -mixed]
Print a list of all active rules in the current session
for the specified language, then exit.
spyglass -printgroups [-verilog | -vhdl | -mixed]
Print a list of all active groups in the current session
for the specified language, then exit.
spyglass -printreportformats Print a list of Registered Report Formats.
spyglass -batch ... run SpyGlass in BATCH mode (Default is GUI).
spyglass -gui ... run SpyGlass in GUI mode. If the default startup
mode has been set as batch through the
configuration file, then this option can override
that default and run SpyGlass in GUI mode.
If both -batch and -gui are specified, then -batch is given higher priority.
All SpyGlass options can be be supplied in a command file as follows.
spyglass -f <command_filename)
-f files can be nested and mixed with command line options.
OPTION DETAILS:
Language Choice:
-vhdl All files are in VHDL.
-verilog All files are in Verilog HDL.
-mixed All files are either in VHDL or Verilog or both.
-def All files are in def format.
Rule-Checking Choice:
-template <methodology-name>/<template-name>
where, <methodology-name> is the methodology and template-name is the
template lying inside the methodology <methodology-name>
Example:
'-template DFT/Latches' will load the "Latches" template of "DFT"
methodology as per the language specified i.e.,
(-verilog | -vhdl | -mixed)
The default behaviour is to load the "Creation" template of "Block-Design"
methodology (Block-Design/Creation), as per the language specified.
-policy=<policy1>,<policy2>....
-policies=<policy1>,<policy2>.... (same as -policy)
where, policy1 and policy2 are supported RuleDeck policies by SpyGlass.
Example:
'-policy=lint' will load the Lint RuleDeck policy.
'-policy=openmore,lint' will run OpenMore and Lint RuleDecks.
-overloadpolicy=<policy1>,<policy2>.... will cause the overloaded version
of specified policy be run, if installed.
-overload=<NamedOverload1>,<NamedOverload2>.... will apply given Named
Overloads, if present, to the specified policies.
-fullpolicy Causes SpyGlass to run all rules of all specified
policies when you have not selected any rules
(only -policies option used and -rules option
not used).
By default, only a selected set of rules are run
for each selected policy.
Checking Session Options:
========================
-rules 'rule_name' Rule or group name to be checked. This option
can specify multiple values if tick or double
quotes is used for specifying argument value.
The default is to check all available rules.
-ignorerules 'rule_name' Rule or group name to be ignored in the rule
checking. The default is no rules should be
ignored. Specifying policy name in place of
rule_name will cause all the rules of that
policy to get ignored.
-norules No rule checking is to be done. Useful when
compiling VHDL libraries.
-ignore_undefined_rules Ignore those rules which are not registered.
Only warning message will appear for
such rules and SpyGlass run will continue.
-addrules <rule-list> runs rules from the <rule-list> in addition to
the rule-set already specified through -rules etc.
-sglib <sglib-file> Specifies the pre-compiled '.sglib' library file
to be loaded.
-plib <plib-files> Specifies PLIB library files. It is recommended to
to compile PLIB library file into an .sglib file
and then use .sglib file for SpyGlass analysis.
-lef <lef-files> Specifies LEF library files. It is recommended to
to compile LEF library file into an .sglib file
and then use .sglib file for SpyGlass analysis.
-sgdc <constraint-file> Specifies the SpyGlass constraints format file
for specification of design constraints to be
used for rule checking.
-dw Enables analysis of DesignWare components
instantiated in the design.
-enable_pgnetlist Enables reading of PLIB files for LowPower Policy.
-noelab Exit SpyGlass after analyzing the design files,
i.e. elaboration does not take place. Useful when
user wants to dump libraries for which elaboration
is not required. No rule-checking is performed.
Reporting Related Options:
=========================
-wdir 'work_dir_path' Specify the directory to be used for keeping
all SpyGlass output files, including .vdb,
.log and schematic data files. The default
is current working directory.
-vdbfile <file.vdb> Define the violation database file -
The default is $(wdirpath)/spyglass.vdb
-logfile <file.log> Define the log file -
The default is $(wdirpath)/spyglass.log
-waiver <Waiver-file> Specifies the SpyGlass waiver constraints format file
for specification of waiver constraints to be
used for rule checking.
-ignorewaivers Ignores the rule waivers due to embedded waiver
pragmas in HDL source description.
-lvpr <number> | The limit on number of violations per rule (lvpr)
-lvpr <rule-name=value> to report; the default is infinity.
Can also be used to specify limit on occurence
of particular rules.
-report <reporttype> When analysis has completed, call the report
generator for the specified <reporttype>.
If this option is not specified then `moresimple'
report is generated.
-noreport No report is generated. Useful if you want to
analyze results separately (in GUI, for example)
-reportfile <file.txt> The generated report is written to this file;
the default file is $(wdirpath)/<reporttype>.rpt.
If you want to see the report on stdout then
use `-reportfile stdout'
-report_max_size=<size> This option provides the flexiblity to change
the sorted report maximum size. By default, the
sorted report size is unlimited and all the
results are shown. However, the user can limit
the size of the report as per need to any
<size> value.
-rulegroup_display_depth=<number> This option provides the flexibility to change
the number of subgroups to be considered for
display in reports and in message Tree.Default value
for this option is 2. If 0 value is specified then
all the subgroups are considered.
-report_per_policy Generate separate reports for each specified
policy.
-report_incr_messages This option is used to set the Incremental Mode
option. This option is useful if you want to compare
the results (messages) of two different SpyGlass runs.
SpyGlass compares the results of the current SpyGlass
run against the results of a previous SpyGlass run.
After the analysis is done with the Incremental Mode
option set, the violation messages in the reports are
categorized into:
* New Messages: These are the additional violation
messages that were not reported in the previous
run but have been reported in the current run.
* PreExisting Messages: These are the violation messages
that were reported in the previous run as well as the
current run.
* Fixed/Missing Messages: These are the violation
messages that were reported in the previous run
but have not been reported in the current run.
reports specific options mentioned in this section
do not affect this section of the reports and this
section is not grouped further.
-old_vdbfile To give the violation database file (vdbfile) of the run
that you want to target as last run. In case this is not
given the SpyGlass will pick up the vdbfile from the
location where it is going to create vdbfile in the
present run.
-define_incr_dirmap This option provides old to new source directory
mapping for spyglass incremental analysis. Old
SpyGlass run might be done for RTL files in
<dir1> while new SpyGlass run can be done for RTL
files in <dir2>. In such a case user needs to
tell SpyGlass that RTL files in new directory
<dir2> are same as those in old direcrory <dir1>
for SpyGlass incremental analysis to work
properly. This mapping can be specified as
-define_incr_dirmap <old_dir> <new_dir>
-sortrule <language>+<rule name>+<sort-order>
Specifies the sort order for messages of a rule
in SpyGlass reports.
-overloadrule <rule name>+<language>+<severity=value><weight=value>
Use this option to overload rule's severity
and/or weight. Please note that all parameters
after rule name are optional. If language is
missing then overload is applied to all existing
personalities of the rule.
-define_severity <policy name>+<severity label>+<severity class>
Use this option to define a new severity label
under a pre-defined SpyGlass severity class for a given
policy.

are loaded from the precompiled libraries specified by this
command-line option. However, such units are synthesized
by SpyGlass.
-checkip <du-name>
Causes SpyGlass to limit rule-checking on specific parts

each rule run and benchmark data for various
stages of SpyGlass run, like analysis, synthesis,
flattening, etc.
(Feature available on 32bit platforms only)
-enable_pass_exit_codes Generates more descriptive SpyGlass Exit Status
Code for successful completion of SpyGlass run.
-lang=<language> Specifies display language of interest. The
display language specification is case-sensitive,
i.e., -lang=ja is different from -lang=JA. The
default display language is English.
-configfile=<config-file> Specified configuration file will be read and
will have priority over configuration files read from
pre-determined locations, namely SPYGLASS_HOME,
user's home directory, and current working
directory.
-support_sdc_style_escaped_name
Allows synopsys-style escaped names in
Spyglass Design Constraint files.
-templatedir Specifies directory from which user wants to
pick a template.It can take single value and
last value overrides all the values given earlier
If not specified Spyglass sets templatedir to
the value specified for DEFAULT_TEMPLATE_DIRECTORY
key in .spyglass.setup
-enable_gateslib_autocompile
Enables auto-compilation of gates library (.lib)
files into '.sglib' library file. The generated
.sglib file ('aggregate.sglib') gets stored in
spyglass cache directory (as specified through
-cachedir option) so that it can be reused in
subsequent spyglass runs
-force_gateslib_autocompile
Forces re-compilation of gates library (.lib)
files into .sglib file. Any data present in cache
directory is ignored. In fact, the cache
directory gets updated with the results of the
current compilation
-cachedir <dir> Specifies the location of cache directory for
storing the auto-generated 'aggregate.sglib' file
during auto-compilation of .lib files. In future,
this cache directory can also be used to store
other spyglass data so that the same data can be
reused across multiple spyglass runs
-disable_gateslib_autocompile
Disables auto-compilation of gates library (.lib)
files into '.sglib' library file if the same has
been enabled via .spyglass.setup file. This
switch is ignored if any of
-enable_gateslib_autocompile or
-force_gateslib_autocompile options is also
specified on the command line
Save-Restore related options:
============================
-enable_save_restore enables save-restore capability in SpyGlass.
-dbdir <database-directory> specifies the design save directory when
working in the Design Save/Restore mode.
-force_save forces design save.
-force_restore forces design restore if possible.
-savepolicy | -savepolicies <policy-name-list>
specifies policies to be saved in addition to
policies given through -policy/-policies option.
-skip_rules_for_fast_restore Disables all those rules which do not allow SpyGlass
to run in full design restore mode.
-nosavepolicy <policy-name-list>
Specifies the policies (not specified with the -policies/
-savepolicies command-line options) for which the
design views should not be saved by default.
SpyGlass options for Power Estimation Policy:
============================================
-target <lib-name-list> Specifies libraries to be used for technology
mapping out of the specified SGLIB libraries.
By default, all specified SGLIB libraries are used
for technology mapping.
-use_scan_flops Causes SpyGlass to use a scan flip-flop if it fails to
find a normal (non-scan) flip-flop for mapping.
-preserve_mux Enables Spyglass to pick mux cells from the technology library
for mapping muxes in a user design.
When this switch is specified, SpyGlass gives priority to the
mux cells present in the technology library rather than a mux
implementation in terms of more basic cells from the technology
library. If mux cells are not present in the technology library,
Spyglass selects the mux implementation in terms of more basic
cells from the technology library.
-sgsyn_clock_gating Causes SpyGlass to create a simple clock gating logic
instead of creating a MUX-based enable logic
when 16 or more flip-flops with the same clock signal
and the same enable signal are found.
Use '-sgsyn_clock_gating_threshold' option to
specify your own number.
-sgsyn_clock_gating_threshold <num>
Specifies the number (default 16) of flip-flops beyond
which SpyGlass create a simple clock gating logic
for flip-flops with the same clock signal and
the same enable signal.
Spyglass aggregate report generation related options:
====================================================
-gen_aggregate_report <report_name>
Used to generate the specified aggregate report. The report_name may
be project_summary or datasheet.
-config_file <config_file> Specify a configuration file having project files path or classic dump directory path
for which aggregate report needs to be generated.
-project <project_file> Specifies the name of a single project file. This option is considered only if the
-config_file option is NOT specified. In such cases, Console accepts the specified
project file as the input. If you have specified both the -config_file and -project
options, Console ignores the -project option and considers the -config_file option.
-aggregate_reportdir <output directory>
The user can optionally redirect generated aggregate reports to a directory specified
with '-aggregate_reportdir". By default, the aggregate reports are generated in
directory "./aggregate_reports".
SpyGlass Exit Code 0 (Informational command executed, rule-checking not done)
