calibre lvs vss vssa vdd vdda
Hi, all,
I am currently doing LVS check on my design. I used digital library that foundary provided. Since , for example inverters, they are pre-defined VDD! GND! already, if I mixed with my own "VDDA" and "VSSA", Calibre gives my an error.
Since I have not included VDD! and GND! in my schematic. (I can see the ports of VDD! and GND! by descending INV).
This kind of mismatching port error gives me an headache.
How do you guys deal with layouts that pre-defined if you want to use your own component?
Thanks,...
