Hi rbugalho,

Thank you so much for the reply. Kindly find attached the modules of the RAM.

1) The module named MEM_2w4r.v is the entire RAM design. - This when synthesized alone , M9K blocks were inferred.

2) The module named test_harness.v is the test harness which is used to wrap the RAM design.

The compilation report gave this message : Info (276014): Found 4 instances of uninferred RAM logic

Info (276004): RAM logic "MEM_2w4r:m0|MEM_1w4r:MEM_1|MEM_1w1r:MEM_1w1r_0|memory" is uninferred due to inappropriate RAM size

Info (276004): RAM logic "MEM_2w4r:m0|MEM_1w4r:MEM_1|MEM_1w1r:MEM_1w1r_1|memory" is uninferred due to inappropriate RAM size

Info (276004): RAM logic "MEM_2w4r:m0|MEM_1w4r:MEM_1|MEM_1w1r:MEM_1w1r_2|memory" is uninferred due to inappropriate RAM size

Info (276004): RAM logic "MEM_2w4r:m0|MEM_1w4r:MEM_1|MEM_1w1r:MEM_1w1r_3|memory" is uninferred due to inappropriate RAM size

The RAM is used in Simple dual port mode, with depth = 256 and width = 32.

Please suggest how I can overcome the issue.
