| openpowerbot | [slack] <Todd Rosedahl> @manikandan_phd I will post here the questions you raised regarding microwatt and Anton's answers. Also information from Mikey. This is the correct channel to ask these questions and get more rapid responses. All members of the channel can see the Q/A and so things do not need to be repeated. You may ask follow up questions to your initial set here. Thank you! | 16:17 |
|---|---|---|
| openpowerbot | [slack] <Todd Rosedahl> Could you please share the design specs of Microwatt ASIC ? | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> How Microwatt FPGA implementation differs from Microwatt ASIC implementation? | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> Idential apart from the RAMs, the register file and the multiplier (which is gate level optimised for sky130). | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> How much die area microwatt taken in the 10 um2 area of efabless? | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> The Microwatt sky130 is not optimised for area at the moment. As an example, we aren't using SRAMs because OpenRAM hasn't been fully qualified on sky130 and are instead using latch based RAMs. The other issue is OpenROAD, which has in the past struggled to route more dense designs. This is improving though. We are likely using about 30% of the area. | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> Is caravel is connected with microwatt in the chip design? | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> We have implemented Microwatt in the user project area of the Caravel chip. | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> Can a Microwatt in the MPW1 chip work independently without the support of caravel RISC V? | 16:17 |
| openpowerbot | [slack] <Todd Rosedahl> The aim is not to require anything from the Caravel chip, and we hope to hold the Caravel RISC-V chip in reset, ie completely unused. | 16:17 |

| openpowerbot | [slack] <Todd Rosedahl> For the design specs for the microwatt ASIC, you can just use the mpw6 link anton setup https://platform.efabless.com/projects/840 which ends up here https://github.com/antonblanchard/microwatt-mpw6 | 16:18 |
