setting SIM_BYPASS_INIT_CAL

Hi, 

 

I am using a DDR3 which I added to my microblaze as a peripheral (mpmc v6.06.a). The simulation of DDR3_SDRAM is quite slow. So, I found on the forum that i need to set SIM_BYPASS_INIT_CAL but i have troubles knowing where to change it! Can you please tell me where can i find the parameter?

Re: setting SIM_BYPASS_INIT_CAL

Hi,

 

You will find mpmc_vx_x_x.mpd in below path, search for calibration bypass/FAST  values, try changing them

........ISE_DS\EDK\hw\XilinxProcessorIPLib\pcores\mpmc_v6_06_a\data

 

I have not tried mpmc so not sure but I see the parameters C_MEM_SIM_CAL_OPTION, C_MEM_CALIBRATION_BYPASS might help you

 

As this is in installation directory better keep an original copy so that you can replace it for synthesis/implementation

 

Regards,

Vanitha
