I am simulating a Xilinx microblaze embedded system using NC-Sim. I am able to load the design, pick signals of interest, and run the simulation. Right after running the simulation the console gives two errors. I don't have them exactly, but it has to do with not being able to write to the SST2 database. I don't have access to the simulator right now so I can't provide the exact error codes. However, things seem to work. I DO NOT know what these errors affect. The only problem I see is that the simulator seems to lock up after running for a long time. I need to sim out to 18,000,000 ps. This is how long it takes the system to initailize to my point of interest. I understand this is an extreme amount of information. Once the sim is done, the software is really slow to respond to changes in the waveform window. If I want to zoom or move the view, I have to wait a few seconds for the screen to refresh. Sometimes, the simulator seems to lock up. The little Windows hour glass shows for minutes and the program gives the "Not Responding" dialog. Is there a reason why it would do this? It takes about 10 minutes to run the simulation to that point, so I don't know if I am hitting memory boundaries or what. Also, once I do get the simulator to successfully get to this point I want to be able to save from here and run simulations from this point forward. I don't care about the initialization. Is there a way to start from an already-simulated point? That way I wouldn't have to wait an extra 10 minutes for the part I don't care about to finish. Long winded.... Thanks!
