synthesis timing improvements

#77 bieganski opened 3 weeks ago

sw: add 'uart_tx_timer_irq' example (with UART).

#76 bieganski opened 3 weeks ago
0
CI: run all ELFs from riscv-tests/isa.

#75 bieganski closed 3 weeks ago

trap is not raised on some unhandled misaligned memory accesses

#74 bieganski opened 4 weeks ago

Adjust make parallelism to use available CPU cores

#73 baiobelfer closed 1 month ago

UART sim: Add '--verbose' switch, to print each instruction executed.

#72 bieganski closed 1 month ago
0
UART simulation: Add possibly infinite mem size option, that auto-adjusts to ELF size.

#71 bieganski closed 1 month ago
0
doc/gdb.md: Mention known GDB segfault bug.

#70 bieganski closed 1 month ago
0
GDB version that we ship segfaults.

change license from MIT to GPLv2

#68 bieganski closed 1 month ago

simplify tests flow (makefile, poetry, build.yml)

#67 bieganski closed 1 month ago
0
CI: simplify build.yml, make any failing step cause job to fail.

#66 bieganski closed 1 month ago
0
fix less-than-word load/store for non-zero addresses (mod 4). NOTE: slight drop in synth timings

#65 bieganski closed 1 month ago
0
uart sim docker test

#64 bieganski closed 1 month ago
0
add CPU+ELF simulation with UART TX->stdout.

#63 bieganski closed 1 month ago
0
WIP fix misaligned mem accesses

#62 bieganski opened 1 month ago
0
AmaranthHDL: bump to 0.5.

#61 bieganski opened 1 month ago
0
docker: bump base image (newest yosys/nextpnr sources: improves synth timings)

#60 bieganski closed 1 month ago
0
AmaranthHDL: bump to 0.4.

#59 bieganski closed 1 month ago
0
Add openOCD co-simulation to CI. Split Dockerfile into to separate ones, (one is mtkCPU-agnostic)

#58 bieganski closed 11 months ago
0
CI: Add bitstream synthesis step. Support only specific gcc version. Avoid 'git rev-parse', as it's not package-friendly.

#57 bieganski closed 11 months ago
0
docker: Add bitstream synthesis capability (requires yosys and nextpnr present in container).

#56 bieganski closed 11 months ago
0
docker: migrate from python:3.10 to ubuntu:22.04 image.

#55 bieganski closed 11 months ago
0
Update to newest Amaranth, fix CI docker container build

#54 bieganski closed 11 months ago
0
implement some openOCD simluation checkpoints

#53 bieganski closed 11 months ago
0
openOCD co-simbulation: Implement checkpoint-based checker framework, in order to automate testing.

#52 bieganski closed 12 months ago
0
CSR: use data.Struct instead of deprecated rec.Record. README: warn users about old yosys version.

#51 bieganski closed 12 months ago
0
fix failing tests issue, introduced by previous commit

#50 bieganski closed 12 months ago
0
cleanup: unused files, CLI --with_virtual_memory switch

#49 bieganski closed 12 months ago
0
README: Add GDB demo Youtube URL

#48 bieganski closed 1 year ago
0
cli/top.py: fix broken gen_linker_script target.

#47 bieganski closed 1 year ago
0
remove unecessary pdf from docs

#46 bieganski closed 1 year ago
0
docs: state long term project goals and contrib rules, add Quick Start section for openOCD+GDB.

#45 bieganski closed 1 year ago
0
DM: Add single-stepping capability (tb + tested with openOCD+GDB on hardware). Refactor main_fsm - Add HALTED state.

#44 bieganski closed 1 year ago
0
DM: minor fixes. halt/resume works with OCD+telnet, memory read works with OCD+GDB (telnet commands are not working well for RISC-V OCD target))

#43 bieganski closed 1 year ago
0
Fix openOCD simulation broken by previous commit, fix DCSR write capture in sim.

#42 bieganski closed 1 year ago
0
DM: Implement 'dcsr.ebreakm' behavior (halt on EBREAK). Add proper testbench.

#41 bieganski closed 1 year ago
0
start.S: Write to 'mtvec' address of mock trap_entry.

#40 bieganski closed 1 year ago
0
cli/top.py entrypoint: cleanup arguments. Define CPU_Config struct, for elaboration variants.

#39 bieganski closed 1 year ago
0
CI: Fix docker image build, fix unit tests.

#38 bieganski closed 1 year ago
0
Add initial support for on-the-board openOCD+GDB. ELF loading and starting works, with Digilent JTAG Adapter.

0
nextpnr: Allow timing check to fail

#36 bieganski closed 1 year ago
0
synthesis: add missing icepack dependency

Add yosys+nextpnr installation snippet for Ubuntu 22.04

#34 bieganski closed 1 year ago
0
Add 'autoexecdata' support in ABSTRACTAUTO. DMI handlers are not 'Elaboratable'. openOCD simulation loads program and starts execution successfully!

#33 bieganski closed 1 year ago
0
Migrate to mainline riscv-openocd. Add ABSTRACTAUTO mock, fix DM testbench, improve openocd TB logging readability.

#32 bieganski closed 1 year ago
0

0
migrate to new openOCD

#30 bieganski closed 11 months ago

DM: handle PROGBUG execution properly (cmderr, halt when execution finishes). Add new testbenches.

#29 bieganski closed 1 year ago
0
DM: PROGBUF gets executed. Add a simple testbench, not yet openOCD tested.
