To accelerate design, I used following commands for multiple CPU processing command in Cadence Encounter APR tcl file: " setMultiCpuUsage -acquireLicense 8 -localCpu max" It seems working fine. For Cadence Virtuoso Calibre DRC/LVS, may I use similar tricks to make it run faster? It's pretty slow for a large design. Also, is (...)

I need some synopsys tetramax help. I have generated compressed and uncompressed serial patterns for a chain test. At the end of of tcl, I wrote the patterns as: write_patterns -format STIL -ser -first 0 -last 0 While the the uncompressed generates pattern0 with load and unload, the compressed generates 2 pattersn (...)
Hi, I'm using the PT(PrimeTime) and ICC(IC Compiler) of synopsys for timing closure. The "fix_eco_timing" command of PT is very powerful for timing ECO. Timing ECO script(tcl) which is generated from "fix_eco_timing/write_changes" command of PT is used for timing ECO in ICC. But this ECO script is for (...)
A design has an address bus 32 bits wide of which only 2 bits go into a module. You create an extra level of hierarchy in DC using the group command and only 2 bits of the address needed go into the newly created module. DC brings in all 32 bits into the module and does not connect the top 30. Is there a way to get rid f the unused bus (...)

You should use Design Compiler (DC) of synopsys. Write a script and use tcl-mode of DC.
They are included in your synopsys distribution and it is called dc-transcript There is also a dc-to-Xg called db2xg
if you are defining link library then use remove_lib else unset link_library. Give synopsys_dc.setup as diff name i.e. synopsys.tcl and then source it.
List is a tcl standard data structure. You can use standard tcl command such as lindex, lappend, ...on it. Collection is synopsys's proprietary data structure behaves like pointer in C/C++. ----------------------------------------------------------------------------------------------- (...)
tcl script is what you used to run your tool, DC for example. SDC is "synopsys Design Constraint" file, this is the constraints that applied to your design. SDC typically used by timing driven place & route tool.
The following is copied from question is : 1)This program only find cells that connect to inout pins directly ,Is it enough and correct just only set_false_path with these cells. 2)From SOLD,just only four path exist ,input to output,input to FF/D,FF/clk to output and FF/CLK to FF/D. the path set by the following (...)
