Is there an approach to save the whole simulation results in Modelsim

Sometimes the simulation in Modelsim will take a very long time. We may check the simulation results just after simulation finished, but may check it again next time (1 day later). In this case, I need to simulate it again and a same long time will be cost. 

 

I just wonder is there any approach that we can save the whole simulation results (the waveform) ? Then we just need to open the simulation results again to check instead of simulate it again.  

 

Thanks very much.

You can add "log -r *" to your .do file before your simulation "run" command. This will create a vsim.wlf that can be opened up later in the GUI to view all the simulation waveforms. However, if you are running very long simulations or have a very large design this might require a lot of disk space. In that case, you can replace the "*" with a particular hierarchal hdl path from your design.

Thanks very much, crauer. Do you know how to operate it through GUI?

Hi crauer, I just find eve I didn't input the comand"log -r *", it seems Modelsim will save the file "vsim.wlf" automatically in each simulation.

Hi all,

 

Is it possible to start the modelsim simulation from the last saved timepoint in wlf file? Or do i need to always restart the simulation?
