Synopsys SpyGlass vQ-2020.03 SP2-3 (Linux) | 15.58 GB | Language: English

Synopsys, Inc., the world leader in semiconductor design software, has unveiled Synopsys SpyGlass vQ-2020.03 SP2-3 – Early Design Analysis Tools Enable Efficient Static Verification of FPGA Designs.

SpyGlass Core
The following enhancement has been made:
– Enhanced SpyGlass by adding an option, named ignore_waiver_file_attr, to ignore the file related attributes (such as -file, -fileline, -filelineblock) in awl file/swl file or both. To enable this feature, set the following option: set_option ignore_waiver_file_attr

Base SpyGlass
The SpyGlass lint, morelint, openmore, starc, and starc2005 products have been enhanced in this release.

SpyGlass lint
The following enhancements have been made:
– W576: Enhanced the W576 rule by adding a parameter, named ignore_conditional_expressions, which when set to yes, enables the rule to not report a violation for conditional expressions of if, generate if, for, generate for, repeat, while, wait and condopstatements.
– W240: Enhanced the W240 rule by adding a parameter, named checkfullstruct, which when set to yes, enables the rule to not report a violation for struct if at least one element of the struct is read.
– W495: Enhanced the W495 rule by adding a parameter, named check_unread parameter, which when set to yes, enables the rule to report a violation for inout ports that are not read. The default value of the check_unread parameter is set to no.
– W224: Enhanced the W224 rule by adding the report_only_from_one_hierarchy parameter which when set to yes, enables the rule to report only one violation per assignment.
– W164a, W164b: Enhanced the W164a and W164b rules to check assign pattern statements where the elements are assigned names or indexes. However, values assigned through data types and default labels are not checked due to the complexity. This feature is enabled when the check_assign_pattern parameter is set to yes.
– W164a, W164a_a, W164a_b, W164b: Enhanced the rules to perform the following when the nocheckoverflow parameter is set to nofor addition, subtraction and concatenation operators:
. W164a, W164a_a, W164a_b: The W164a, W164a_a, and W164a_b rules will not report a violation if the maximum value of the RHS expression is within the width of the LHS signal.
. W164b: The W164b rule will not report a violation if the LHS width lies in between the natural width and the LRM width.
. W164a: The W164a rule reports a violation width that will be the natural width when the LRM width of the RHS is more than the natural width.
. W164b: The W164b rule reports a violation width that will be the LRM width when the LRM width of the RHS is more than the natural width.
SpyGlass morelint
The following enhancements have been made:
– ParamValueOverride-ML: Enhanced the ParamValueOverride-ML rule to report entries related to the module only if there are overridden parameters in the module in the ParamValueOverride_Report.rptreport.
– ImproperRangeIndex-ML: Enhanced the ImproperRangeIndex-MLrule by adding a parameter, named report_loop_var_expr, which when set to yes, enables the rule to report a violation for index expressions with for loop variables by considering the maximum value of the loopvariable. The maximum value of the loop variable is determined using the initial and conditional expressions of the for loop. The rule reports a violation for the integer loop variable when both the report_loop_var_expr and ignoreInteger parameters are set to yes.
SpyGlass openmore
The following enhancement has been made:
– CombLoop: Enhanced the CombLoop rule to report mutually exclusive loops in the default flow and added a parameter, named check_loop_breakers, which when set to yes, enables the rule to not report a violation for mutually exclusive loops.
SpyGlass starc, starc2005
The following enhancements have been made:
– STARC- Enhanced the STARC- rule to report a violation width (when the nocheckoverflow parameter is set to no for addition and subtraction operators) that will be the LRM width when the LRM width of the RHS is more than the natural width.
– STARC05- Enhanced the STARC05- rule by adding a parameter, named ignore_system_tasks, which when set to yesenables the rule to not report a violation for system tasks.
– STARC05- Enhanced the STARC05- rule by adding a parameter, named report_only_from_one_hierarchy, which when set to yes, enables the rule to report only one violation for the function, when the same function is included in different hierarchies.

SpyGlass CDC
The following enhancements have been made:
– License Changes: For all features that require the Advanced_CDC license, SpyGlass CDC now requires the following additional license key:
. cdc_adv_checker
For the RDC flow, SpyGlass CDC now requires the following additional license keys:
. cdc_adv_checker
. rdc_adv_checker
Refresh the existing license file to access the new features.
– Clock_info05, Clock_info05b: Enhanced the Clock_info05 and Clock_info05b rules by adding a constraint, named filter_clock_overlap, to specify the hierarchical nets and hierarchical pins for filtering converging clocks.
. SGDC_filter_clock_overlap01: Enhanced SpyGlass CDC by adding a rule, named SGDC_filter_clock_overlap01 to report a violation if non-existent objects are specified in the -clocks argument of the filter_clock_overlap constraint.
. SGDC_filter_clock_overlap02: Enhanced SpyGlass CDC by adding a rule, named SGDC_filter_clock_overlap02 to report a violation if non-existent objects are specified in the -conv_net argument of the filter_clock_overlap constraint.
. FilterClockOverlapSetup: Enhanced SpyGlass CDC by adding a rule, named FilterClockOverlapSetup to report cases in which the filter_clock_overlap constraint is not used to waive any of the clock_info05 / clock_info05b violations in the design.
– Clock_info05, Clock_info05b: Enhanced the Clock_info05 and Clock_info05b rules by adding a parameter, named report_unused_converging_clocks, which when set to yes, reports all the clock overlaps on a mux/gate. These clock overlaps are not used by the sequential elements and they reach another clock.
– Ac_Abstract_validation02, Ac_glitch03: In the hierarchical SoC flow, SpyGlass includes the -single_non_quasi argument in the generated abstract_port constraint if a non-quasi source is reaching the output port through a combinational logic. This enables the Ac_Abstract_validation02 and the Ac_glitch03 rules to consider such combinational paths as buffers and therefore the rules do not report a violation for such cases.
