raybox-zero

Accomplishments

harden_test.sh updated to support more-complex args:

$ ./harden_test.sh -h
Usage: ./harden_test.sh [OPTIONS] [SELECT]
OPTIONS can include:
    -h          Show this help.
    -t STRING   Include STRING as an extra heading in the summary file.
    -o OUTFILE  Specify output summary file instead of default timestamped stats-*.md
    -f          Force overwriting of OUTFILE if it already exists.
    --          Stop processing options; remaining arguments are literal.
SELECT, if provided, is an extended regular expression that will specify which combos to run.
It gets matched against the name of each combo:
    4x2:1 4x2:2 ... 4x2:5
    8x2:1 8x2:2 ... 8x2:5

harden_test.sh includes more info in summary file:
- tt04-raybox-zero last commit
- Included src/raybox-zero last commit
- Tag (if -t given in args)
- Options used
- Start/finish timestamps
test001-notex-notracetest: Integrated stuff from yesterday (no 'tex'), and merged TraceStep/TraceTest states.
- Merged states mean 1 state per ray step instead of 2 (trace completes in half the line time).
- Runs fine in sim.
- Subtle difference: Only seems to be relevant when player is inside a wall cell (which is out-of-bounds anyway).
test002-vdistreg: Branched off test001 to try using a register for visualWallDist (to avoid dual post-subtractors in a mux).
- Runs fine in sim.
- Subtle difference: Subtle difference is that when walking into a wall cell, the effect is as though we've 'stuck' at the last rendered size. This is fine and probably better than what test001 is doing (though neither should matter).

Various tests

Baseline: height_scaler merged into wall_tracer FSM using shared_reciprocal

Click for details...

Code:

tt04-raybox-zero: 6b0e41e: Combo 5 added to harden_test
- Equivalent to: 7aae611: Wire up SPI for fixed pov
src/raybox-zero: 5408d42: Add in winrand.bat for sim build on Windows
- Equivalent to: ff05791: Fix map size parameters

Summary:

Using shared_rcp branch for all
height_scaler already merged into wall_tracer shared_reciprocal
MAP_* parameter use fixed in rbzero.v
TRACE_STATE_DEBUG option exists, but all such options are disabled (i.e. no map overlay, no debug overlay, no trace state visualisation).

Findings:

Combo 5 fits in 4x2: 60.51% util out of possible 65%, with 25MHz achieved.
8x2:2 can hit 50MHz.
8x2:3 FAILED. I'll avoid running combo 3 in future because I've had it hang other times too.
Combo 4 max speed is about 42.4MHz out of target 50MHz.
Typical start cells is ~15k, final ~9.7k
Not sure why synth results are a bit larger than in previous runs. Probably bad luck with yosys randomness from source formatting.

test001: Merged TraceStep/TraceTest; commented out 'tex' logic

Click for details...

Code:

tt04-raybox-zero: c452d31: harden_test: Adding a little more stats data
- Equivalent to: 7aae611: Wire up SPI for fixed pov
src/raybox-zero: 84edb52: test001: Merged TraceStep/TraceTest; commented out 'tex' logic.
- Equivalent to: ff05791: Fix map size parameters

Summary:

Commented out 'tex' logic. Probably makes little difference; synthed out anyway?
Merged the TraceStep and TraceTest states. This works because we have 0-WS map ROM access, but slightly change the initial condition logic (but not in a way that should matter, i.e. I think only different if the player is standing in an occupied map cell)?

test002: Registered visualWallDist avoids post-subtraction

src/raybox-zero: 03f53f3: test002: Registered visualWallDist avoids post-subtraction

Summary:

visualWallDist was calculated by 'back-stepping' trackDist, with a mux based on side.
This test changes it to a register that directly records the distance previous value while trackDist advances.

Findings:

Combo 8x2:2 fits and gets 50MHz.
Overall, this IS a little better: Slightly faster, slightly less area.
8x2:4 faster for ~same area: 45.13MHz vs. 44.86MHz.
4x2:4 ALMOST fits in 60% util.
Antennas are a little worse.

Findings:

This is generally worse. Surprising, esp. given synth_cells and logic_cells both reduce.
Area doesn't really change (though it is a tiny bit worse in most cases).
Speed is poor, but that might be due to assumptions that STA is making about input data changing into the shared_reciprocal when it actually doesn't?

Next steps

Check vdist: it seems to be Q7.9??
Change visualWallDist reg to something like Q8.12
Instead of rayAddendX <= -(vplaneX<<<8)-(vplaneX<<<4), require host send us a negated vplane, then start from the positive side and adding vplane will be deducted -- same result?
Make rcp_in a register instead of mux.
Any way to replace multipliers with incremental adders?
WIP test005: Reduce trackInitX/Y to a single shared multiplier, and cap it based on partials being <= 1.0 and both inputs always being positive...? Note also that partials are only used for trackInit, so maybe there's a way to change the maths to a smarter shared module that takes advantage of the ranges of ALL inputs (playerFrac, rxi, stepDist).
- Would shmul be better if it used register inputs instead of mux?
- Loading mapX/Y doesn't need to be restricted to TracePrepX. Can we set "don't care" in Verilog?
stepDistY probably doesn't need to be a reg: given it is the 2nd reciprocal and its value gets used immediately to make trackInitY, and then continuously in TraceStep, it could probably just be replaced with rcp_out.

Later

Multipliers could be allowed to lose precision with bigger numbers? e.g. very far view distance doesn't need precision for texture column selection (or even scaling).
Run harden_test.sh in GHA
Split reicprocal into multiple stages (states) to avoid excessive multiplies and combo chains. Even consider using a conventional accurate reciprocal?
Try using "smart LZC".

Notes

Overnight harden_test got stuck on an 8x2:3 again. See log below. I re-ran it all except combo 3s: time ./harden_test.sh :[1245]
