Occasional Contributorproblems find when simulate UniPHY + DDR2
IP: UniPHY with DDR2 controller
Quartus Prime Standard 18.0
Simulation: Nios 2 + Uniphy + Micron DDR2 (MT47H128M16)
Modelsim-intel is used.
Problem: it stops during ddr2 initialization phase....
Hi Xiaoqiang Shen,
UniPHY simulation does not adhere to the initialization timing to speed up the simulation so it will fail when using the Micron memory model. I assume the simulation passes with the DDR2 example design with Intel generated memory model. As a workaround, you can comment out the initialization time check in the Micron memory model.
Hope this helps.
Thanks,
Rashmi

ContributorDoes this latest sim run much longer than the previous simulation? It should if you are running full calibration
