Not able to generate the antenna info for hard blocks

tswong

I've done the steps below to generate the antenna info on abstract generator, but it is fail so far..

1) define the thickness and defaultantenna rule for electricalRules section on techfile.

2) turn on the signal tab of Extract step

3) define "drain" and "gate" for antenna calculation

There is no error message during the generation, but it is still not able to find any antenna information at the exported LEF. I am not sure whether anything is missed. I wonder anyone could give me advise!
