Minimum II of 2 but HTML report has no further information

HRZ,

Thanks for the insight. I had not considered nested loops, and experimenting with that produced something interesting. I removed the inner loop and just did the calculations on one bank to test things out. I also unrolled a for loop I used to implement the shift regs (idx_pipes, etc) so that there were no nested loops inside the 'outer' loop. Now the tool still shows an II of 2 on the 'outer' loop except now it provides more info. It does say there's a store dependency on those two lines. I wouldn't expect that behavior because it's a doublepumped memory (2 wr ports, 2 rd ports).

Do you have any advice on that?

EDIT: This is with version 17.0.
