Need help for setting up xc7s50t

Hi, I’m trying to add support for xc7s50t to Project X-Ray. Naturally I refered to the Guide to adding a new device to an existing family and tried to pick up where #1534 left. However it seems that the Project X-Ray toolchain has changed quite a bit since #1534 and the guide is about how to add devices to existing families instead of adding new devices of new families, so I’m currently stuck at where I’m supposed to make db-prepare-artix7. For context, I’m on Ubuntu 20.04.3 with Vivado 2017.2 installed and successfully ran Step 9 (the 010-clb-init fuzzer) of the Getting Started section of Project X-Ray’s documentations (ran ./download-latest-db.sh in Step 8) for artix7. A minor problem occured when running make env of Step 5 (see my comments on #1521 ) but that didn’t prevent me from proceeding.

Here’s what I did after completing 010-clb-init for artix7:

• Created spartan7.sh and spartan7_50t.sh in prjxray/settings. The content was mostly copied from /prjxray/settings/spartan7.sh and /prjxray/settings/spartan7_50.sh in the spartan7_50 branch of @litghost’s prjxray fork.
• Created device.yaml in /prjxray/setting/spartan7.
• Added spartan7 as a new argument to update_parts.py and update_resources.py in /prjxray/utils.
• Added Spartan-7 info to Makefile

Then in a new terminal, following the instructions in Guide to adding a new device to an existing family, I ran make db-prepare-spartan7 and got the following output:

me@me-my_machine:~/prjxray$ make db-prepare-spartan7

Which already looks wrong, compared to what make db-prepare-artix7 gave me:

me@me-my_machine:~/prjxray$ make db-prepare-spartan7

Then source settings/spartan7.sh returned this:

me@me-my_machine:~/prjxray$ source settings/spartan7.sh
Traceback (most recent call last):
  File "/home/me/prjxray/utils/create_environment.py", line 66, in <module>

    assert part, "Part {} not found in {}".format(part, part_mapping)

Because prjxray/database/spartan7/mapping/parts.yaml contains only {} and nothing else.

Did I miss something? How should I solve this? Thanks!

A new prjxray-db was published with this initial spartan7 support @ https://github.com/SymbiFlow/prjxray-db/tree/master/spartan7

The HTMLified version can be found at https://symbiflow.github.io/prjxray-db/#database-for-spartan7 with the HTML rendered tile graph found at spartan7.

@bunnie I see. My goal is to allow SymbiFlow to be able to generate bitstreams targeting Spartan-7 from user HDL designs, preferrably using the Yosys-VPR-FASM-Bitstream flow (which would require me to get the RR graph and arch.timing.xml) since it already supports a few Artix-7 parts, while nextpnr says their support for Project X-Ray is still under development.

@acomodi Thanks! I’ll look into this Interchange thing.
