  28. b283c6f Added separate counter top register to PWM devices. This stores the full mask allowing more control over the clock frequency.

  42. 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, 7 months ago
  43. 7d855db Added core architecture simulation. Currently this will only work locally with some other applications installed. Already used this to fix AUIPC instruction not actually adding the program counter, by Charlie · 2 years, 7 months ago
  44. bf7d214 Added assignments to unused input pins, this helps GL simulations work now that input pins are actually connected. 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, 7 months ago
  45. 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, 7 months ago
  46. 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, 7 months ago
  47. e67733d Added CSR registers to core. These include the basic counters and status registers. by Charlie · 2 years, 7 months ago
  48. 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, 7 months ago
  49. 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, 7 months ago
  50. 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, 7 months ago

  61. 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, 7 months ago
  62. 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, 7 months ago

  65. fdffa98 Merge branch 'Development' by Charlie · 2 years, 7 months ago
  66. 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, 7 months ago
  67. 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, 7 months ago
  68. 273a77b Fixed directory that GitHub workflows checks for finding precheck results. by Charlie · 2 years, 7 months ago
  69. dd6cb52 Merge branch 'Development' by Charlie · 2 years, 7 months ago
  70. 9cc2031 Reverted to older OpenLane version, as it seems this is a requirement for MPW submission. by Charlie · 2 years, 7 months ago

  78. 4443fea Added read back of test memory to core program counter test. by Charlie · 2 years, 7 months ago
  79. 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, 7 months ago
  80. 951f5a3 Updated GitHub workflow to harden and test the correct modules. by Charlie · 2 years, 7 months ago
  81. 2ccd997 Merge pull request #3 from Wevel/Development by Wevel · 2 years, 7 months ago

  90. e312600 Updated GPIO test to set the success pin high before the test starts, so that if it fails on the first test its more clear. by Charlie · 2 years, 7 months ago
  91. 7d7207a Updated testing setup to remove example tests, and provide a proper GPIO test which passes when using verify rtl. by Charlie · 2 years, 7 months ago

  94. 8b2f283 Fixed wishbone slaves not providing read data on the correct clock cycle. by Charlie · 2 years, 7 months ago
  95. 025b919 Fixed user macros not being connected to PDN. Rotated SRAM macros are still not connected, so the full build still fails. by Charlie · 2 years, 7 months ago
  96. 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, 7 months ago
  97. c6f707b Added info on tests that need to be implemented. by Charlie · 2 years, 7 months ago
  98. 8afd017 Fixed core 1 SRAM macros not having the correct orientation. by Charlie · 2 years, 7 months ago

  100. d6dcdf1 Updated collated logs after previous build. by Charlie · 2 years, 7 months ago
