Branch Quicklogic : The no of PB-5XGMUX available shows only 1. #1554
Comments

So currently the GMUXes are modeled as a single tile that contains 5 GMUX sites. That tile (actually the top-level pb_type in VPR) is named PB-5XGMUX. So there is one tile with 5 GMUXes that's why VPR reports it as only one. Unfortunately, the model does not work correctly as there is no control which one of these 5 GMUXes is chosen during packing/placement. The solution that is being worked on. It includes modeling the GMUX tile as 5 separate tiles with one GMUX site in each. In both cases the total number of GMUX cells is correct. Expect a pull request soon with the fix. |

The issue should be already fixed as QuickLogic-Corp#34 had been merged. |
