ERROR: Multiple modules are selected.

[alain6666]

hi, i have a project with multi verilog file and multi module, i use the moosic in a yosys script to encryption the project as below:

But I received the following error message

How should i do?

[Coloquinte]

Moosic doesn't support hierarchical projects at the moment. What happens here is that multiple modules are selected in Yosys, and locking each of them separately is likely not what the user wants. Two possibilities:

• run "flatten" on your design, so that all logic is in one module
• select a single module (cd command in yosys, I think) to lock only this module; you want a module that is flat with a lot of logic (typically alu or instruction decoder). Since its interface is going to change, you need to handle the new "moosic_key" port in its users.

What I do in my TinyTapeout example is to synthetize the locked module separately, then save it as verilog, and start from there with the rest of the design.

Keeping this open until I come by with a better error message
