* Fix .qip file, add missing PLLs Fix a problem with Quartus build where four `.qip` files, for four different PLLs, were missing. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Update to Chisel 7.3.0 Update all Chisel code to the latest Chisel (7.3.0). This has the major effect of changing the underlying FIRRTL compiler used to build the Verilog from the Scala-based FIRRTL Compiler (SFC) [[1]] to the MLIR-based FIRRTL Compiler (MFC or `firtool`) [[2]]. Additionally, as ChiselTest [[3]] is archived/unmaintained, this switches all the testing to use the newer Chisel testing framework, Chiselsim. A number of modules are sensitive to initialization conditions. This is exposed when switching to Chiselsim as it will use `initial` block randomization by default. Treadle, the default simulator when using ChiselTest, would initialize everything to zero. E.g., the cache doesn't appear to clear its tag bits on reset. This manifested with one test failing because the cache would transition to evict instead of fill (likely because the tag bits indicated that the line was dirty). Anytime this occurred it likely indicates bugs in the design. However, practically these shouldn't manifest as FPGA flows tend to zero-initialize everything in the bistream. (And empirically, the core has been working!) Because of the switch to ChiselSim, this will now pull in a dependency on Verilator to run tests. Other miscellaneous changes include fixing deprecations/removed functions (like the change around `MuxLookup`), removing width inference of a few output ports for modules used in tests (which is now illegal on public modules), and updating the mill build flow to use the latest version of mill. Verilog generation is now one-file-per-module under the `quartus/cave/` directory as opposed to a single file `quartus/cave.v`.

Unfortunately, this needs a Verilator version _newer_ than what is provided by the Ubuntu 24.04 (`ubuntu-latest`) GitHub runner. That only provides 5.020 which has a bug in Verilator throwing a spurious `WIDTHEXPAND` warning (which is fixed in newer versions). Grab the latest OSS Tabby CAD suite which has a newer version of Verilator. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * [rtl] Add Chisel 7.3.0 Verilog, update .qip Add the newly-generated Cave Verilog files, removing the old `Cave.v`. Because it is highly advised to have `firtool` generate Verilog one-file-per-module, that is done here. All generated verilog files are put into the `quartus/rtl/cave/` directory. Update the `quartus/files.qip` to reference these new files. It is my understanding that `.qip` doesn't support a wildcard import. Hence, this is a bit brittle in that it lists out all the Verilog files one-by-one. As long as generated Verilog files are committed to this repo, this will be a maintenance issue. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * squash! [rtl] Add Chisel 7.3.0 Verilog, update .qip Disable all randomization when generating FPGA Verilog (and in the resulting, committed Verilog). There's no reason to include this as none of this is enabled for the Quartus flow. This will save on the committed file size and also make the output Verilog more readable (though still generated). If there was any simulation of this Verilog, it would make sense to keep this. * [dep] Bump Chisel to 7.5.0 Bump Chisel to the latest release, 7.5.0. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Fix compile-time deprecation warnings Fix all compile-time deprecation warnings stemming from everything in `firrtl` being deprecated and the deprecation of `BlackBox` in favor of `ExtModule`. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * fixup! [rtl] Add Chisel 7.3.0 Verilog, update .qip * Omit version comment in generated Verilog Add the `omitVersionComment` option when generating Verilog to stop emitting the "Generated by ..." version comment. Normally this is useful, however, given the fact that this project commits the generated Verilog, it would be better to omit this to decrease the amount of churn due to Chisel version changes. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Regenerate Verilog from Chisel 7.5.0 Regenerated the Verilog using Chisel 7.5.0. There are no meaningful changes other than one internal name change. (This is a bug in upstream Chisel which someone is taking a look at.) Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Bump Chisel to 7.6.0 This includes a naming improvement when using `FlatIO`. This was necessary as part of the simplest `BlackBox` -> `ExtModule` migration, but included a naming regression that was identified here and then fixed in Chisel 7.6.0. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Regenerate Verilog using Chisel 7.6.0 Regenerate Verilog pulling in slightly improved Verilog names. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com> * Bump Chisel to 7.7.0 Bump Chisel version. There are no changes to the emitted Verilog.

Made with ❤️ by Josh (nullobject) Bassett, 2022.
This project is based on the prior work of Rick (rwk) Wertenbroek, who reverse engineered DoDonPachi for his master's thesis back in 2019. I would like to thank him personally for his technical guidance along the way, and providing me with source code for his original prototype.
I would also like to give a massive shout out to all my Patreon supporters. Your support keeps me working on these games, and helps bring them to everybody in the MiSTer community.
