The terms back -annotation and forward -annotation refer to a process for using that data. SDF contains constructs for the …

WebUsing "Fake" Hold Times for GLS with SDF It takes a lot of engineering man-hours to get SDF annotated GLS working. And this work must be started *before* your netlist is anywhere hear hold clean. But since, SDF Timing GLS cannot be run without a hold clean netlist, one trick is make a script to fake-fix hold on your netlist.
