| hackerfoo | mkurc: Would you like to work on creating the other IOPAD variants? (containing IOB33S, IOB33 (single))? IOB33S should be the same but with "SELECT_Y 0", the single pads might not be much more work. | 17:02 |
| hackerfoo | I'm not sure what's involved in getting VPR to treat the tiles as equivalent. | 17:02 |
| hackerfoo | And then we'll need the left variants eventually. | 17:03 |
| sf-slack3 | <mkurc> @hackerfoo: I can work on that. From my understanding if those tiles are to be equivalent then we do not need to have different models for them. Just a generic one. I'll do some research on that starting from tomorrow. | 18:01 |

| lromor | Hello everyone, I was wondering what synth_tiles_pinmap.csv contains. Could someone give me a brief explanation? | 19:46 |
| litghost | It maps pad locations to the VPR grid locations, which is required for IO placement constraints | 19:49 |
| lromor | thanks! Noted | 19:52 |

| lromor[m] | * nice, thanks! I'll test the pr. what if I wanted to contribute and map some of the remaining pins? | 22:27 |
| litghost | There is an active effort to remove the ROI, but in the mean time you can modify the prjxray harness creation to include your PIN | 22:28 |

| lromor[m] | Thanks! I have everything built locally so it won't be a problem. Could you elaborate why there's an effort of removing the ROI? What does that mean? | 22:30 |
| litghost | Currently we have Vivado build us a "harness" that handles the IO stuff so we could initially focus on LUTs/BRAMs/FFs, etc | 22:31 |
| litghost | We no longer require the harness, and are working on removing it, which would allow mapping of any available pin without modifying the harness | 22:32 |
| lromor[m] | Ah. I see. Thank you. | 22:33 |
