Hello All,
I am trying to find leakage of different instances/subckts using spectre xps.
I tried using
chk1 dyn_subcktpwr inst=
[*] port=
[*] depth=4 time_window=[36n 37n]
It dumped an empty xml file.
Then moved ahead with spice commands as under:
For
.probe i(vvdd)
.probe i(vvcs).
I am measuring them as under:
.measure tran leak_vdd_1 avg i(vvdd) from = start_time to = end_time
.measure tran leak_vcs_1 avg i(vvcs) from = start_time to = end_time
But how to measure current for below probe which used isub
.probe isub(SEGIOX2.VDD)
.probe isub(SEGIOX2.SEGIO0.VDD)
.probe isub(SEGIOX2.REBUF.VDD)
I tried following ways which did not work.
1) .print isub(SEGIOX2.VDD)
2) .measure tran leak_vdd_2 avg i(SEGIOX2.VDD) from = start_time to = end_time
So any help on how to dump current probed by isub ?
Thanks,
Roopak
