8cbc9f7e51 Wrote a bash script to generate custom modelsim radix which maps instruction addresses into human readable lables.
Once combined with some simulation verilog this will display the current function in modelsim.

not sure what to do about MMU yet, hopefully we'll decide at saturday's meeting

ca546beaf8 We now have a solid rough draft of the 2 bit sat counter branch predictor with BTB and RAS.
This is not yet tested but the system verilog does compile.

935e9e59e9 added branch predictor 2 bit table + SRAM model. The SRAM model is only approximate, but it does correctly model the read and write pipelined behavior. 2021-02-14 15:13:55 -06:00

f789e9c8ba Due to legacy code, make pnr would print out an internal Makefile error at the end of the run. While this error was inconsequential and did not affect anything, it still needed to be removed. 2021-02-14 13:43:30 -06:00

8486f426b7 The top level of the branch predictor built and compiles. Does not yet function. Missing the BTB, RAS, and direction prediction tables. 2021-02-14 11:06:31 -06:00

bd99a5613a sky130 18T and 15T cell libraries removed
Upon noticing their size, concerns were raised about available drive space.
As 12T is the main implementation focus, the decision was made to remove 15T and 18T.

Apologies if any were interested in implementing the processor across multiple standard cell libraries for comparison.

555e0296b2 After going through Lab 3 again, I've decided to make small changes to the provided floorplan so that it may serve as a slighly better example of a good floorplan. 2021-02-14 04:43:07 -06:00

1ea01389b9 Final changes to the lab3 branch
- Removed manual register file placement script, as it has been removed from lab.
 - Created pre-sets that only have to be uncommented for the changing clock target portion of lab.
 - Cleaned up Makefile in case anyone looks inside of it.

eab780afb9 - Cleaned up unnecessary files
- Pulled updates for std cells
 - Fixed typo that prevented easy switching between standard cell variants
 - Fixed asynchronous reset paths from not being flagged as false

84d856d1e5 busybear: allow testbench to ignore lack of MMU for now
I'd really like to go over this with someone else, not sure if this is
a good thing to be doing

If it is, we're at 1M instructions!

e89af96bc0 busybear: more updates
now gets to instruction 839037 before failing
also updates to match new gdb output format

umm there seems to be something wrong with the SSTATUS CSR. Just leaving
it out for now, will come back and check it later

f08e549118 gdb output combine script updates
check that everything is actually the same instruction
update to new 4-file output

this file should be finished for now
