| sf-slack | <sdamghan> Thanks @mkurc , I tried to utilize this feature in tcl script, however, it seems for `keep_hierarchy` attribute it is not effective. It is worth noting that once I used (* keep_hierarchy *) for the same module inside the Verilog code it works as expected. `Tcl script: read_verilog -nomem2reg spram.v setattr -mod -set keep_hierarchy 1 spram ...` `Spram.v module spram (inputs, output) ...` In this scenario, once I use | 01:16 |
|---|---|---|
| sf-slack | `flatten` in Yosys, the spram will change to Yosys internal memory. However, in the following case: `Spram.v` `(* keep_hierarchy *)` `module spram (inputs, output)` `...` Yosys works as expected and does keep the spram module intact when I output a coarse-grain netlist. | 01:16 |

| jn | Hi, a prjxray question: i ran download-latest-db.sh in the prjxray repo, and it cloned the auto-generated database repo. which file do i have to pass to nextpnr-xilinx with the --chipdb option? | 19:55 |
| jn | (for context: i want to run a minimal yosys+nextpnr flow for my artix7 board) | 19:56 |

| gatecat | jn: https://github.com/gatecat/nextpnr-xilinx#building-the-arty-example---xray-database hopefully still works | 21:10 |
| jn | it fails to find tilegrid.json: FileNotFoundError: [Errno 2] No such file or directory: '/home/user/git/nextpnr-xilinx/xilinx/python/../external/prjxray-db/artix7/xc7a100tcsg324-1/tilegrid.json' | 21:17 |
| jn | which is in the xc7a100t directory, AFAICS | 21:18 |
| jn | (i.e. the directory without the package type and speed grade in the name) | 21:18 |
| gatecat | right, it's not been maintained for a long time and only ever been tested with whatever old prjxray-db version it includes as a submodule | 21:19 |
