Examples of using PSL for functional and formal verification of VHDL with GHDL (and SymbiYosys)
A Dockerfile with a collections of ready to use open source EDA tools: Yosys, SimbiYosys (with Z3, boolector and Yices2), nextpnr-ice40, netxpnr-ecp5, nextpnr-gowin, Amaranth HDL, Silice and Verilator.

Logic Analyzer IP Core
Bazel rules for Symbiyosys.

SymbiYosys (sby) Formal Verification
Prettyosys is an easy-to-use and visually appealing wrapper for Symbioysys
Configurable CRC-8/16/32 hardware core — RTL, formal verification (SymbiYosys/Z3), Yosys synthesis, and SKY130A GDS tape-out
RTL bugs found via formal verification — SymbiYosys + Z3
Формальная и функциональная верификация переходника с интерфейса valid-ready на интерфейс valid-credit.
Formally verified round-robin arbiter — 6 SVA properties, formally closed, SymbiYosys + Z3
Formally verified synchronous FIFO — SVA + SymbiYosys + Z3
Sync, async (dual-clock CDC) & AXI4-Stream FIFOs in SystemVerilog — formally verified (SymbiYosys BMC + k-induction + liveness), Verilator-simulated with coverage closure, and FPGA-characterized (ECP5 + iCE40).
Synchronous FIFO — simulated, formally proven (SymbiYosys), synthesis-gated
Formally verified AXI4-Lite slave — SVA + SymbiYosys + Z3, 21 assertions, 15 cover properties, k-induction depth 20
