[topgen] Array of inter-module signal
This commit is to support an array of inter-module signals.
To achieve the array feature in inter-module, regardless of the act
(requester, responder/receiver), the key shall be an array and the
entries should be `width` as 1. So, inter-module signal only supports
1:1, 1:N, N:1.
Also, the top-level signal name follows the key instance name not
'req->rsp' as before.
```hjson
inter_module: {
'module_a.sig_a': ['module_b.sig_a', 'module_c.sig_a']
}
```
In the above example, `sig_a` in `module_a` can be requester or
responder/receiver. The `width` of `module_a.sig_a` shall be 2.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can either access it online or build it locally by following the steps below.
$ sudo apt install curl python3 python3-pip $ pip3 install --user -r python-requirements.txt
$ ./util/build_docs.py --preview
This compiles the documentation into ./build/docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:1313.
