I am designing a VCDL for DLL. But the PSS analysis is not converging. I am trying to change "reltol" value but @ very begining of simulation it is showing a warning
'reltol' is not a valid parameter for an instance of `pss' . Ignored
Can anyone tell me if I can change reltol value at all in PSS analysis?
reltol is an options parameter ("spectre -h options") not an analysis specific parameter. You can use errpreset to affect the reltol, but if you want to set reltol you'd do:
myOpts options reltol=1e-5
