BMM Flow
The EDK tools Implementation Tools flow using Data2MEM.
ngdbuild -bm <system>.bmm <system>.ngc
map
par
bitgen -bd <system>.elf
BitGen outputs <system>_bd.bmm that contains the physical location of BlockRAMs. The
<system>_bd.bmm and <system>.bit files are input to Data2MEM. Data2MEM translates
contiguous fragments of data into the proper initialization records for Virtex series
BlockRAMs.
Reserved MHS Parameters
PlatGen automatically expands and populates certain reserved parameters. This can help
prevent errors when your peripheral requires information on the platform that is
generated. The following table lists the reserved parameter names:
