Hello all,I am currently running a CONFORMAL (R) Constraint Designer v10.10 check for an IP which consists several *.v files.In one of the .v files the "generate" statement has been used -- This is causing an error while I run my CCD script.-----------------Error msg given by compiler:// Parsing file ~hdl/abc.v ...// Error: hdl_default_checks/rtl_checks/RTL13.6: Standalone generated blocks are not supported in the IEEE standard// In line 235, file '~hdl/abc.v'// Error: Fail to read design.// Read design summary: Error: 1, Warning: 0, Note: 0-----------------CCD script which reads the design file:read design -verilog2k -define <company_tech_name>\-root <....> \-parameter <...> \hdl/some_file.v \hdl/abc.v \hdl/some_file.v \-lastmod -noelab-------------------------Please throw some light on the RTL13.6 error message and tell me which switch I shall use witn the "read design" command so that the error message regarding use of "generate" statement in design dosen't show up?
Hope I am clear in the explanation!
A standalone generate block is one in which the generate construct contains content outside a generate-if/case/for.
The 'wire x;' declaration does not appear inside a generate if/for/case.
This is legal in Verilog-2001, but not in Verilog-2005 and SystemVerilog.
Maybe Conformal has a switch to tell it to use the 2001 version instead of the 2005 versio.
Or you can tell Conformal to treat this as a warning instead of an error.
In reply to Shalom B:
Yes, that's what I believe too, that the "read design" must be having a switch!
You see in my 1st post, I am already using the switch " -verilog2k " but that dosen't solve the problem.
I have checked the Conformal_Ref.pdf documentation for all switches belonging to the cmd "read design", but couldn't find it there.
Also it is no use changing an Error to a Warning! Coz if my script cannot parse the design file, it is no use running the constraint.
I am using CCD for the 1st time & have no experience!
In reply to dp2402:
R&D made RTL13.6 an error in 10.1. It went back to a warning within 2 months. You could download 11.1 or do 'set rule handling RTL13.6 -warning' if continuing with 10.1.
In reply to croy:
Just when I thought my problem is solved, CCD now says that RTL13.6 is an unknown rule!
But if I run the script without the 'set rule handling ....', compiler gives error:
// Error: hdl_default_checks/rtl_checks/RTL13.6: Standalone generated blocks are not supported in the IEEE standard
:( Can't understand what's happening!
Please use 10.10-s280 or later.
set rule handling hdl_default_checks/rtl_checks/RTL13.6 -severity warning
Thanks a lot Chrystian.
