mithro | opps wrong channel | 16:44 |
sf-slack | <acomodi> @mithro: some of the tests in symbiflow (carry-stress) are autogenerated (both design, and constraints file) based on tests parameters defined in CMake, and all the tests are generated for each board/device. | 16:49 |
sf-slack | <acomodi> mithro: After synthesys, some of the tests for ice40 do not have all the IO signals connected, therefore VPR produces a packed netlist without the unconnected IO signals. | 16:49 |
mithro | @acomodi: Can you be more specific about what is unconnrected? | 16:49 |
sf-slack | <acomodi> mithro: https://pastebin.pl/view/6a94be86 | 16:52 |
tpb | Title: Untitled - Pastebin (at pastebin.pl) | 16:53 |
sf-slack | <acomodi> In the paste there, there is the design, the output eblif and the PCF. The carry_fabric signal is the unconnected signal in this case, which is present in the PCF | 16:53 |
sf-slack | <acomodi> I believe that another solution would be to add a fix to the IO placement script that generates the placement constraints for VPR, so that it avoids outputting the constraint itself, if the related signal is unconnected. I need to check if this is easily doable | 16:55 |
