Hi!
Could anyone explain, what are route-throughs in look up tables and why
are they used? When I run the map command (xilinx) on my design, I get
in the report file (design.mrp) a section:
Design Summary:
Number of errors: 0
Number of warnings: 3
Number of CLBs: 124 out of 324 38%
CLB Flip Flops: 81
4 input LUTs: 203 (3 used as route-throughs)
3 input LUTs: 68 (13 used as route-throughs)
Number of bonded IOBs: 62 out of 144 43%
IOB Flops: 0
IOB Latches: 0
Number of clock IOB pads: 1 out of 8 12%
Number of primary CLKs: 1 out of 4 25%
Number of startup: 1 out of 1 100%
Thanks in advance
Frank
