GHDL Back in Debian

Mon, 06 Aug 2018 22:48:12 +0200

As I have noted, I have been working on packaging the VHDL simulator GHDL for Debian after it has dropped out of the archive for a few years. This work has been on slow burner for a while and last week I used some time at DebConf 18 to finally push this to completion and upload it. ftpmasters were also working fast, so yesterday the package got accepted and is now available from Debian unstable.

Reviving GHDL in Debian

It has been a few years since Debian last had a working VHDL simulator in the archive. Its competitor Verilog has been covered by the iverilog and verilator simulator packages, but GHDL was the only option for VHDL in Debian and that has become broken, orphaned and was eventually removed. I have just submitted an ITP to make my work on it official.

A lot has changed since the last Debian upload of GHDL. Upstream development is quite active and it has gained free reimplementations of the standard library definitions (the lack of which frustrated at least two attempts at adoption of the Debian package). It has gained additional backends, in addition to GCC it can now also use LLVM and its own custom mcode (x86 only) code generator. The mcode backend should provide faster compilation at the expense of lacking sophisticated optimization, hence it might be preferable over the other two for small projects.
