 23 Jan 2008 5:52 .tch file for qrc |
|
|
|
Hi,
I have a .tch file which i use for extraction using qrc. I understand that .tch file is a binary file created from .ict file using techgen.
I dont have the .ict file from me. Is there any way I can see the contents of the the .tch file?? (similiar to libgen -ls showing the summary of the .cl library)??
Regards

ICT file is from the UMC fab and .tch is from the TSMC fab so in order to get the ict file u need to ask ur vendor thts wt i can say

| It is possible to generate ( recover) ICT file from .tch file. I do not rember exectly what was commend for that but it should be there in RCGen's command manual or you can ask for command to cadence support

i was having a related doubt with the extraction,,,,,,
as a input qrc tool,,we generally provide qrcTechfile,,,,, one tech.lef file which contains information about the layers resi,cap....etc, and one macros lef which gives information about the metal layers consumed by the macros,,,,
so my doubt is when qrcTechfile has all the information required to estimate the resistance of the metals,, why the tech.lef file is required ?
