I'm trying to get Quartus Prime Standard 16.1 to output SDF in order to do a gate-level simulation (in Modelsim). I have a detailed set of instructions, which were last updated for Quartus (II/Prime?) 15.0. I am following these, but no SDF is output. Has something changed since 15.0?Needless to say, I have gone through all the settings and have searched the web and this forum for help. But no joy. Here is the relevant bit of my instructions:
What device? I believe gate-level timing simulations are not supported in most newer devices. They take too long and don't show anything that wouldn't come up in an RTL simulation and static timing analysis, so people stopped doing them.
Ah...interesting. I trying 10M08DAF484C8GES. The original (Quartus 15.0) instructions were for a Cyclone IV device and I am trying to update them and, for consistency, changed the device to this Max 10 device. (It doesn't actually matter what device is used.)Thanks for your reply.
Yep...I think you're right. I just tried a Cyclone IV device and voila: SDF files aplenty. Thank you.Coming from an IC background, not running a timing sim seems a bit scary.
