Hi there
I find 3 short errors after nanoroute. They are always detected on a particular CKBUF cell. One of the error is as following:
SHORT: Regular Via of Net a25_simple_alu/FE_OFN343_o__rhs_18_ & Blockage of Cell a25_simple_alu/FE_OFC343_o__rhs_18_ ( M1 )
Below left figure is the cell with via (M1 in blue) in p&r and right shows its layout (M1).
The problem is reported on the bottom via in the left which connects to pin Z.
After measurement, no short should happen btw this via to internal different nets.
I didn't make any blockage for the cell. And no use even applying "fixvia -short".
Can anyone share the experience on this issue?
