go-vcd-parser reads Value Change Dump (VCD) files, the waveform format that simulators such as Verilator, Icarus Verilog and nvc write.

Reusing the general approach from this post gives a way for setting Shift_L+Shift_R as layout change: $ gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Shift>Shift_L']" $ gsettings set org.gnome.desktop.wm.keybindings switch-input-s…

From zero to RISC-V in hardware, in 6 minutes Program your FPGA with a one-liner command.

Be forewarned: HER builds with nix require a functional ranlib This is something seldom known, and a very sharp corner to cut yourself on.

bazel rules for GHDL I present to you https://github.com/filmil/bazel_rules_ghdl: a set of bazel rules for converting VHDL into Verilog.

bazel rules for a riscv64 bare metal rust compiler This article assumes that you have bazel installed via the bazelisk method.

bazel installation via the bazelisk method Here is how I install bazel.

bazel rules for a riscv64 bare metal GCC compiler The repository https://github.com/filmil/bazel_rules_gcc_riscv64_baremetal contains bazel rules that can be used for a hermetic bare metal GCC cross-compiler for a 64-bit RISC-V machine, running in M-mode.

Summary Here is how you can set up a hardware server (hw_server) in AMD Vivado 2023.2.

Google Nest Router (2nd Generation) can serve as an access point I accidentally bought the Google Nest 2nd Generation Router when I needed an Access Point.

Summary This short note defines the notions of hermetic, ephemeral and reproducible software build, as used in my writing.

Summary I bother with bazel.

You, too, can have a fully hermetic, reproducible, and ephemeral bazel build.

Docker tips and tricks Save an image to an archive docker save imagename | gzip > myimage.tar.gz Load image to an archive docker load < myimage.tar.gz

Bazel does not like FIFOs Perhaps obvious in retrospect, but it is not possible for a bazel build artifact to generate a named pipe in the filesystem.
