The current scenario of HDL open-source simulators has changed significantly, raising the question of what cases traditional commercial simulators are still necessary.

GHDL and NVC are advancing quickly towards full VHDL 2008 compliance in addition to experimental VHDL 2019 support in NVC. Mixed language simulation has been a challenge with open-source tools, previous attempts used language translation to convert Verilog to VHDL and vice versa. Recently, NVC has added experimental support to Verilog, opening the path to true mixed language simulation with open-source tools. This presentation intends to show the capabilities of open-source simulators, compare these with commercial solutions and discuss the current challenges with open-source tools.
