SETUPHOLD and SETUP in one SDF ?

setuphold sdf

Hi all,

I am writing a SDF with version 3.0 using pt. Is it possible to have both SETUPHOLD and SETUP/HOLD constructs in one sdf for one cell instance?
I need this because one of my verilog model of a cell has this kind of requirement. In this model, one condition is described as SETUPHOLD while some other condition is mentioned as SETUP only. But SDF has all SETUPHOLD and tool can't annotate this.

$setuphold updated format

Why do you need this? How could PT use setup and hold at the same time? Doesn't it do the setup and hold checks separately?
