NAME
ghdl - VHDL compiler/simulatorSYNOPSIS
ghdl [command] [options] files...DESCRIPTION
This manual page documents briefly the ghdl command. This manual page was written for user of man, but is not as complete as the reference documentation.Instead, users should read the GHDL texinfo manual
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of the main modes and options is included below. For a complete description, refer to the GHDL texinfo manual.Basic commands:
- -a
- Analysis, i.e. ghdl -a file.vhdl
- -e
- Elabortation, i.e. ghdl -e unit_name
- -r
- Run: run the simulation, i.e. ghdl -r unit_name
- -s
- Syntax-check, i.e. ghdl -s file.vhdl
- --clean
- Clean: remove generated files, i.e. ghdl --clean
- -h, --help
- Help, i.e. ghdl --help
- --version
- Version, i.e. ghdl --version
Basic options:
- --work=NAME
- Name of the WORK library, i.e. ghdl -a --work=foo foo.vhdl
- --std=STD
- Which VHDL standard (87|93|93c|00|02), i.e. ghdl -a --std=87 old.vhdl
- --ieee=VER
- Which IEEE library (none|standard|synopsys|mentor), i.e. ghdl -a --ieee=synopsys broken.vhdl
- --no-vital-checks
- Disable VITAL restriction checking, i.e. ghdl -a --no-vital-checks unsupported_vital.vhdl
There are many more modes and options; please consult the documentation.
Executables created by GHDL have addition simulation options. The most important ones are listed below:
- --help
- Show options for simulation and execution.
- --assert-level=LEVEL
- Assert level at which to stop simulation (none|note|warning|error|failure), i.e. ./touchy_design --assert-level=note
- --stop-time=TIME
- Stop simuation after TIME, i.e. ./design --stop-time=50ns
- --vcd=FILENAME
- Dump VCD to FILENAME (a waveform dump, viewable with--for instance--gtkwave), i.e. ./design --vcd=design.vcd
- --sdf=[TYPE=]PATH=FILENAME
- Back annotate SDF onto design using TYPE (min|typ|max), instance PATH, and SDF file FILENAME, i.e. ./sdf_design --sdf=typ=top/inst=inst.sdf
