Description-en: VHDL compiler/simulator
GHDL is a compiler and simulator for VHDL, a Hardware Description Language.
GHDL is not an interpreter: it allows you to analyse and elaborate sources to
generate machine code from your design. Native program execution is the only
way for high speed simulation.
.
GHDL offers three machine code generation backends: one based on GCC, one
using the LLVM compiler suite and a GHDL specific one called mcode. These are
available in the ghdl-gcc, ghdl-llvm and ghdl-mcode packages respectively.
Both the GCC and LLVM backends create highly optimized code for excellent
simulation performance while simulations compiled with the GCC backend also
allow coverage testing using gcov. The mcode backend creates less performant
code but makes up for it with much faster compilation. It is therefore
preferable for smaller projects without large or long running simulations.
.
Multiple backends can be installed at the same time and selected by either
invoking the desired GHDL directly (as ghdl-gcc, ghdl-llvm or ghdl-mcode) or
by providing a GHDL_BACKEND environment variable (containing gcc, llvm or
mcode) while invoking ghdl.
.
This package is a dependency package that will make sure at least one backend
is installed.
