command line version of generating layout tree file

xPeDoTx 9 months ago

hi,

im looking for a command line version of generating layout tree file.

from layout view we can do it by Edit->Hierarchy->Tree or using shift+T.

i have been using and big fan of the sch hier tree skill code solution from following article for a while now.

https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/41566/config-view-assignment/1360121#

i need the command line version to include in my perl / bash script.

i did try to modified the sch version by changing some possible relevant information of sch to lay but getting no where.

im not very good at skill code but willing to give a shot if anyone can point out some direction.

Thanks.

When calling abSchTree(), you should pass ?useViewSwitching nil as a pair of arguments amongst the other arguments you are uto stop it trying to switch views (from symbol to schematic when traversing schematic hierarchies). That should be all you need.

However, since you're running from a UNIX perl/bash script, you could use the "fastTree" command that we ship with Virtuoso. See Virtuoso Layout Suite L User Guide -- Working With Hierarchical Designs - Using the Print Hierarchy Tree Command (the command is in <ICinstDir>/tools/dfII/bin and if you run "fastTree" with no arguments it will tell you how to use it). Note that this fastTree doesn't support schematics (as it doesn't do view switching) but it certainly would work for layout.

hi Andrew Beckett , This is exactly what I'm looking for. i never knew the existence of the fastTree command. Now i don't need to modify the schTree to make it work on layout. Thank you for pointing this out. Really appreciate it.
