• 2026-10-15 rules_fusesoc: FuseSoC Cores as Bazel Dependencies #bazel#FPGA#RISC-V

  rules_fusesoc integrates FuseSoC, the FPGA core package manager, into hermetic Bazel builds. Users declare desired core libraries and IP dependencies in Bazel build files. The module resolves dependencies and exports …

• 2026-09-24 grlib: Gaisler’s GRLIB and the NOEL-V Core as a Bazel Module #bazel#FPGA#RISC-V

  The grlib Bazel module packages GRLIB, Gaisler’s (Frontgrade’s) GPL VHDL IP library, so that the NOEL-V RV64 RISC-V core and the AMBA infrastructure around it can be consumed as ordinary Bazel dependencies. It is the …

• 2026-09-03 rules_vivado: FPGA Synthesis and Place-and-Route in Bazel #bazel#FPGA#Vivado

  rules_vivado drives the AMD/Xilinx Vivado FPGA toolchain from Bazel: compile, simulate, synthesize, place-and-route, generate a bitstream, and program the device, all as ordinary build actions instead of clicks in a GUI …

• 2026-08-17 Bazel all the way down: how I build programmable hardware #bazel#FPGA#HER

  This is a description of how I build programmable hardware. Everything that goes into Cocoapuffs (my RISC-V system-on-chip on an Artix-7 FPGA), including the RTL, firmware, simulations, synthesis, bitstream, and board …

• 2026-07-19 Booting Fuchsia’s Zircon on a homebrew RISC-V SoC, on an Artix-7 FPGA #FPGA#RISC-V#Zircon

  Fuchsia’s Zircon kernel now boots on Cocoapuffs, my homebrew RISC-V system-on-chip on an AMD Artix-7 FPGA. As far as I know, this is the first Fuchsia boot on programmable hardware. Below you will find the boot video and …
