| litghost | Agreed. My original plan was to require [IO]BUF and BUFG's explicitly, but this can neatly solve that | 14:57 |
| mithro | Litghost: https://github.com/SymbiFlow/symbiflow-arch-defs/pull/939 - does this help/solve the slack issue? | 15:57 |
| tpb | Title: Add fast path timing for better hold slack estimation. by litghost · Pull Request #939 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 15:57 |
| litghost | No, it just gets a better hold slack estimate | 16:10 |
| mithro | kgugala: I added comments to https://github.com/SymbiFlow/symbiflow-arch-defs/pull/703 | 16:53 |

| sf-slack2 | <kgugala> @mithro can VPR handle separate <blif_model> tags? | 17:00 |
| sf-slack2 | <kgugala> or we'll need additional step before feeding the xml to vpr? | 17:00 |
| mithro | kgugala: No but we transform them here -> https://github.com/SymbiFlow/symbiflow-arch-defs/blob/19660cdc6a5997d924425160560177dc6af51724/common/xml/convert-pb_type-attributes.xsl#L7-L16 | 17:01 |

| sf-slack2 | <kgugala> oh, ok | 17:01 |
| litghost | mithro: Can you explain the attribute -> tag move? It seems pretty arbitrary, and without value | 17:08 |
| mithro | litghost: It allows pb_type files to be composed | 17:09 |
| mithro | litghost: Previously you had to look into the pb_type.xml file and copy the blif_model tag to the pb_type tag you were adding | 17:09 |
| sf-slack2 | <frenebo> Hi, I was wondering if any of you have seen this project: https://theopenroadproject.org/ It looks like this project looks somewhat similar to what Symbiflow intends to do for FPGAs. | 19:31 |
| tpb | Title: OpenROAD Foundations and Realization of Open and Accessible Design (at theopenroadproject.org) | 19:31 |
| sf-slack2 | <frenebo> "Prof. Kahng and the OpenROAD team are aiming to develop open-source tools that achieve autonomous, 24-hour layout implementation." | 19:31 |
| mithro | fenebo: Yes, I talk to Prof Kahng every couple of months | 22:08 |
| mithro | We are likely to collaborate around the SystemVerilog tooling improvement work we are just starting | 22:09 |
