- c678a2e Fixed ALU immediate instructions producing the wrong result if the aluAlt bit is set, even when this signal is not used in the instruction. by Charlie · 2 years, 6 months ago

Also made some ease of use changes, such as adding a script to copy simulation results, and automatically copy guide file when regenerating guide view. by Charlie · 2 years, 6 months ago
- 600ce3a Re added ore PC GL simulation to GitHub workflow. Between this and the GPIO test, it should ensure nothing major is missing from the SoC, and these simulations should be just about fast enough to run. by Charlie · 2 years, 6 months ago
- 1a18a97 Added additional modules to variable dump after GL simulations. This means that its actually possible to see what's happening on the wishbone bus in the event of a simulation failing. by Charlie · 2 years, 6 months ago
- e67733d Added CSR registers to core. These include the basic counters and status registers. by Charlie · 2 years, 6 months ago
- 753ef0c Added JTAG core management controller. This is untested and don't use a standard method of using JTAG for managing a core. However, if it works, a custom interface could be written to allow programming the core over JTAG. by Charlie · 2 years, 6 months ago
- 9e72728 Fixed gpio not getting input connections (a bit more) due to verilog being dumb and not correctly parsing a mux inside a mux when performing syntheses, even though it works correctly in rtl simulation. by Charlie · 2 years, 6 months ago
- 626c8dc Fixed GL simulations not working properly due to missing pullup on mprj_io[3]. This is needed to make sure the management core doesn't end up in an invalid reset state. Also fixed nextTest method which wasn't correctly setting the test passed pin low if a test failed. This uncovered a some mistake made in the GPIO, memory, and UART tests, which are now also fixed. These included input pins not being connected to anything within the peripherals macro. by Charlie · 2 years, 6 months ago

- e88c884 Fixed timing valid pin being inverted when output error in video test. by Charlie · 2 years, 6 months ago
- b2e455b Added video device simulation test, and new VGA state register which contains synchronisation signals. Also fixed some issues with register addresses, and the VGA signal generation. The video test doesn't currently validate that the correct pixels are displayed, but it does test the synchronisation times. by Charlie · 2 years, 6 months ago
- 2746c44 Made fixes to UART device and caravel host to enable UART-rtl test to pass. Also updated corePC test to use the newer GPIO registers. by Charlie · 2 years, 6 months ago

- fdffa98 Merge branch 'Development' by Charlie · 2 years, 6 months ago
- 7e13152 Removed art from art module so that it doesn't cause DRC errors (this will be changed back when a fix for this is found). Also added set, clear, and toggle registers to gpio for easier control. This also makes it easier for both cores to write to gpio without clearing what the other core has set. by Charlie · 2 years, 6 months ago
- e4118ea Renamed Counter.v to use the upper case first letter. This allows the file to be used when building on case sensitive file systems. Strangely this wasn't a problem when using Ubuntu through WSL. by Charlie · 2 years, 6 months ago
- 273a77b Fixed directory that GitHub workflows checks for finding precheck results. by Charlie · 2 years, 6 months ago
- dd6cb52 Merge branch 'Development' by Charlie · 2 years, 6 months ago

- 4443fea Added read back of test memory to core program counter test. by Charlie · 2 years, 6 months ago
- c138fb0 Added core program counter test. Also fixed the core not putting any of the core in the macro. This was caused by the unimplemented JTAG device not sending a signal to the core management, preventing it from ever allowing the core to run, resulting it being optimised away. by Charlie · 2 years, 6 months ago
- 951f5a3 Updated GitHub workflow to harden and test the correct modules. by Charlie · 2 years, 6 months ago
- 2ccd997 Merge pull request #3 from Wevel/Development by Wevel · 2 years, 6 months ago

- b8c7bb2 Made some small changes to try to get PDN to connect to macros. Also fixed some missing logic in the core macro. However, most of the macro still does not get built. by Charlie · 2 years, 6 months ago
