14:18 <sf-slack> <p.vanleeuwen> Hey there! I'm working on my graduation thesis (CS) in which I analyse FPGA emulation (specifically, the ECP5). For this, it would be very helpful to have a graph/network model of an FPGA. The Trellis project collected the information that I need, but I can't seem to find how to extract the (connectedness) information from this project. The JSON files are only machine-readable and the HTML documentation seems

14:18 <sf-slack> sparse as well (I have no background in hardware / FPGAs). Can anyone recommend me how to obtain this connectedness information / graph model? Any help would be greatly appreciated:D Best regards, Pim

14:41 <daveshah> .mux is for programmable connections, and .fixed_conn <dst> <src> for fixed connections

14:41 <daveshah> There's a normalisation scheme, so E3_ for example is a reference to a named wire in the grid location 3 to the east

22:45 <sf-slack> <timo.callahan> Hi all, is there an existing test/demo for Symbiflow + Litex/VexRiscV + Linux targeting Arty A7 35T? I know of the Vivado-based example (https://github.com/litex-hub/linux-on-litex-vexriscv), and Symbiflow+Linux on Zynq (https://github.com/antmicro/symbiflow-linux-guide), but not exactly the combination I mentioned. Thanks for any tips!
