M1-Pre: How to get MAP to report number of flip-flops, LUTs used

Description


The design.mrp file will reveal statistics on device utilization, as

shown here:

~~~~~~~~~~~~~~~~~

Design Summary:

Number of warnings: 90

Number of errors: 0

Number of CLBs: 922 out of 1024

Number of external IOBs: 138 out of 160

Number of BUFGLSs: 3 out of 8

Number of RPM macros: 9

~~~~~~~~~~~~~~~~~~



However, note that there is no report of the number of flip flops or

LUT (look-up tables).

解决方案


To have map report this information, set the environment

variable XIL_MAP_BEL_CNT to 1, and run map. You may set

this variable on your UNIX workstation by typing:



setenv XIL_MAP_BEL_CNT 1



Once this has been done, and map has completed, the design

summary will show the following:
