User Guide: DSim Input Filename Examples

Each input filename is decomposed into one or more extensions, each starting with the . character. Both the primary and secondary extensions, if they exist, can be used to indicate information about the file contents.

The primary extension can be used to indicate that a file is compressed and to identify the type of compression used.
In the absence of compression, DSim uses the primary extension to decide which language specification to apply to the file.
When compression is present, DSim uses the secondary extension to decide which language specification to apply.
By default, DSim interprets the extension .v as Verilog and .sv as SystemVerilog. All other extensions are unknown and the file will be interpreted as Verilog.
To customize the list of recognized extensions, use the -sysvlog-ext and -vlog-ext command line options. For more information see the Common Options section. Including the . character in each extension is optional.

DVlcom uses the same methods of determining Verilog and SystemVerilog when parsing files.

DVhcom is only capable of parsing VHDL files so there is no need to distinguish the extensions.

Filename	Options	Assumed Language	Compression
`test.sv`		SystemVerilog
`test.sv.gz`		SystemVerilog	gzip
`test.sv.bz2`		SystemVerilog	bzip2
`test.sv.tmp.gz`		Verilog (default)	gzip
`test.SV`		Verilog (default)
`test.SV`	`-sysvlog-ext .SV`	SystemVerilog
`test.SV.gz`	`-sysvlog-ext .SV`	SystemVerilog	gzip
`test`		Verilog (default)
`test.svh test.svp`	`-sysvlog-ext svh:svp`	SystemVerilog
`test.vh test.vp`	`-vlog-ext vh:vp`	Verilog
`test.vh.gz test.vp`	`-vlog-ext vh:vp`	Verilog	gzip or none
