Description

It would be awesome if you had a "information from tape outs" type page in the documentation somewhere. I would like to see it have the following information;

- [ ] What was taped out
- [ ] Who it was taped out with (IE Foundry, Node, PDK, Process, etc)
- [ ] What type of tape out it was, test chip, production run, etc....
- [ ] What tools were used
- [ ] What was the resulting gate count
- [ ] What was the resulting silicon area usage (mm x mm)
- [ ] Some performance / energy specs.

The idea is to quickly get an idea for;
- [ ] How frequently the core is being taped out.
- [ ] What the most popular way to tape out the IC is (who is being used, what node, etc)
- [ ] Ballpark around expected size and performance

There is some great information in the "Slow and Steady Wins the Race? A Comparison of
Ultra-Low-Power RISC-V Cores for Internet-of-Things Applications" paper you link too. However, it would be good to have a quick summary to look at.

FYI The information from that paper says;
> Zero-riscy is 2.2× smaller than Riscy and provides a 2× energy boost for mixed control/arithmetic code with limited DSP. Micro-riscy is 1.6× smaller than Zero-riscy (∼11.6 kgates in UMC 65nm), has a power envelope of just 100μW at 160MHz and it is 1.4× more energy efficient than Zero-riscy on pure control code.

Research direction

Start by locating the repository's documentation area and reviewing the linked “Slow and Steady Wins the Race?” paper for the tape-out details mentioned in the issue. Define the page's scope, gather comparable tape-out information, and document the requested manufacturing, tool, area, gate-count, performance, and energy fields; done means the summary supports the proposed comparisons.
