Answers Database M1-Pre: How to get MAP to report number of flip-flops, LUTs used Record #1637 Product Family: Software Product Line: FPGA Implementation Product Part: map Problem Title: M1-Pre: How to get MAP to report number of flip-flops, LUTs used Problem 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). Solution 1: 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: ~~~~~~~~~~~~~~~~~ Design Summary -------------- Number of warnings: 90 Number of errors: 0 Number of CLBs: 922 out of 1024 Flops/latches: 738 4 input LUTs: 1678 3 input LUTs: 478 Number of external IOBs: 138 out of 160        IO flops/latches: 0 Number of BUFGLSs: 3 out of 8 Number of RPM macros: 9 ~~~~~~~~~~~~~~~ End of Record #1637 - Last Modified: 12/31/96 13:54
