Measuring Leakage current in a Big Schematic using XA/HSPICE/HSIM

*Set accuracy level to 6

.option xa_cmd="set_sim_level 6"

*Doing operating point analysis

.op

*Optional, but good to have a probe point – helpful if the XA run takes a lot of time to run

.probe i(vvdd) i(vgnd)

*Can measure the ‘transient’ current through VDD – that’s leakage current (if no other nodes are switching)

.meas tran vdd_cur i(vvdd)

Can you provide please more information about the set_sim_level command? i.e, how to apply it and description of each level 1,2,3, etc? is there a document that contains that information?
