  1. Closed: How to get_attribute of a user defined attribute in a timing lib in PrimeTime?

    I have a set of timing libs i get from other design teams. They add a custom user defined attribute of class "lib_timing_arc" to timing arcs.

    All i have is the .lib files. Im reading them into...
  2. Closed: How to pass arguments to PrimeTime TCL script? (using pt_shell -file myScript.tcl )

    I want to allow user to pass some variables (lib file path, some constraint values, etc). How can i do that with a PT -file command?

    eg. In tcl file i want to have:
    set timing_lib_path [lindex...
  3. Closed: Re: In PrimeTime, how can I view setup/hold times per endpoint in easy format for par

    Wow, thanks man. I'm new to this whole EDA tool analysis so I didnt know what you meant. Now it's so much better!
    Do you mind telling me what you exactly searched up on Google? Just so I know the...
  4. Closed: Re: In PrimeTime, how can I view setup/hold times per endpoint in easy format for par

    I know how to use TCL with PrimeTime, but how can i use it to parse the reports? The commands dont return a list/collection/array, they just return the text AFAIK
  5. Closed: In PrimeTime, how can I view setup/hold times per endpoint in easy format for parsing

    Hello, Im trying to output setup/hold times for synchronous endpoints into a side report.

    Im using the below, but it only shows me slack in easily parsed format. If i use -path_type full, Itll...
  6. Closed: In PrimeTime, whats are -start_end_pair and -cover_design in report_timing cmd?

    Hello,

    Im trying to view setup and hold times, but i cant seem to figure out the difference between the following:


    (for either min or max delay type):
    report_timing -path_type summary...
  7. Closed: How do I know inbetween which pins do arcs exist in PrimeTime for timing libs?

    Hi,
    I want to basically print all setup and hold and delay times between all paths.
    I want to print them whether they violate or not, basically to do comparison analysis between this lib and...
  8. Closed: Re: How to save PrimeTime command output into a variable in TCL?

    Thank you.

    foreach p [get_pins -filter {is_clock_pin}] { puts "[get_object_name $p]\n" }
    instX/pinX instX/pinY

    They are now printed as 1 single variable, however if I do this command:
    %...
  9. Closed: How to filter ICC2 violations in a certain x-y rectangle of the design?

    In ICC2 gui, im able to open error database and set type, layer, net filters as well as region filter whcih i could drag my mouse to a certain area to only show the errors in that physical area. I...
  10. Closed: How to save PrimeTime command output into a variable in TCL?

    Hello,
    I've used a few EDA tools with their TCL commanders in the past and now exploring PrimeTime.... the regular method seems to not work, not sure why. Can someone explain what's happening?
    ...
  11. Closed: In PrimeTime, how can I report_delay_calculation from all input pins to all out pins?

    Hello,
    In the timing libs, I can find the "output" ports, see their "Related_pin", and report delay calculation from related_pin to output_port. However, how can I do this for all output ports and...
  12. [SOLVED]Closed: Can you use StarRC to extract a certain subcell and all its connections to topcell?

    Hello, my team is working on RC extraction from layout for certain subcells inside a big layout. We don't want to extract the whole thing because the extracted netlist will be huge and take long.

  13. Closed: Re: Why do I get duplicate markers when loading and outputing a Calibre results datab

    I know, but I want the original DB with hierarchy for review purposes. But I am writing a flow (for other purposes) that takes in 2 DBs, and to make sure that my flow can work on the DBs, I want them...
  14. Closed: Why do I get duplicate markers when loading and outputing a Calibre results database?

    Hi,

    I have a hierarchical Calibre reuslts violation markers database, meaning it tells me in exactly which subcell each violation belongs to, and coordinate in that subcell context, and properties...
  15. Closed: Re: Can you create a unique signature from a GDS polygon shapes?

    Okay, lets say the shapes are the same and cells are the same 2 different gds. How can I get a unique signature for shapes+cells and ignore any text labes in the GDS? md5sum wont work for the GDS...
  16. Closed: Re: Can you create a unique signature from a GDS polygon shapes?

    I see. That actually merges multiple layouts.

    Actually, I use layout filemerge to merge multiple rule GDS into 1, but i guess that doesnt merge the shapes.

    You are right....
  17. Closed: Re: Can you create a unique signature from a GDS polygon shapes?

    Can you elaborate? I wasn't able to find anything about "merge" in the reference manual, not even remotely. Thanks
  18. Closed: Can you create a unique signature from a GDS polygon shapes?

    Hello,

    My company uses Calibre for layout manipulation.

    I'm exploring an idea where we can convert a DRC violation markers database into a layout/GDS (done), then create a unique signature...
  19. Closed: Re: How to use ICC2 to merge 2 LEFs into 1 monolithic LEF?

    I'm trying to automate this process. I'm not very familiar with SKILL in Virtuoso and find myself working better with ICC2. I deal with Calibre for layouts, and I'm not sure I can read in LEFs in...
  20. Closed: How to use ICC2 to merge 2 LEFs into 1 monolithic LEF?

    Hi all,

    I have 2 LEFs, one is an actual macro LEF, and the other is a "boundary" LEF to be abutted to the actual macro.

    I want to shift the boundary LEF to the left a bit, then merge them...
  21. Closed: Re: How can you use Mentor Calibre to flatten a hierarchical DRC database?

    Hi, you're right. With the -dt expand, my result rdb had MANY MANY more markers but all at the same location of the original 4 markers.

    When i turned off that option, my result rdb now is...
  22. Closed: Re: How can you use Mentor Calibre to flatten a hierarchical DRC database?

    I'm the tech file? I'll check it out soon but that still will only give me a DB with hier count markers (ie. Not the flat DRC marker count).

    I want both DBs, flat and heir, not just one of them....
  23. Closed: How can you use Mentor Calibre to flatten a hierarchical DRC database?

    Hello,

    When I run DRC -hier, I get a rule violation markers database hierarchically. The DB shows exactly in which subcells each violation is in, along with properties such as the rotation factor,...
  24. Closed: In a GDS with multiple cells in parallel (no one topcell), how can I create a topcell

    Hello,

    I have a GDS (library of cells), where all cells are in parallel. There isn't a topcell.

    For example, you'll see this hierarchy:
    -cell1_horizontal
    -cell1_vertical
    -cell2
    -cell3
    ...
  25. Closed: How can you run Calibre -drc both FLAT and HIERARCHIAL?

    I know to run fat DRC, you run calibre -drc
    but to run hier DRC, you run calibre -drc -hier
    But each option produces one report and one database of the violation in the option (hier or flat)...
