vhdlpp COMMAND LINE FLAGS:
|
|
|
|
-D <token>
|
|
Debug flags. The token can be:
|
|
|
|
* yydebug | no-yydebug
|
|
|
|
* entities=<path>
|
|
|
|
-L <path>
|
|
Library path. Add the directory name to the front of the library
|
|
search path. The library search path is initially empty.
|
|
|
|
-V
|
|
Display version on stdout
|
|
|
|
-v
|
|
Verbose: Display version on stderr, and enable verbose messages to
|
|
stderr.
|
|
|
|
-w <path>
|
|
Work path. This is the directory where the working directory is.
|
|
|
|
|
|
LIBRARY FORMAT:
|
|
|
|
The vhdlpp program stores libraries as directory that contain
|
|
packages. The name of the directory (in lower case) is the name of the
|
|
library as used on the "import" statement. Within that library, there
|
|
are packages in files named <foo>.pkg. For example:
|
|
|
|
<directory>/...
|
|
sample/...
|
|
test1.pkg
|
|
test2.pkg
|
|
bar/...
|
|
test3.pkg
|
|
|
|
Use the "+vhdl-libdir+<directory>" record in a config file to tell
|
|
Icarus Verilog that <directory> is a place to look for libraries. Then
|
|
in your VHDL code, access packages like this:
|
|
|
|
library sample;
|
|
library bar;
|
|
use sample.test1.all;
|
|
use bar.test3.all;
|
|
|
|
The *.pkg files are just VHDL code containing only the package with
|
|
the same name. When Icarus Verilog encounters the "use <lib>.<name>.*;"
|
|
statement, it looks for the <name>.pkg file in the <lib> library and
|
|
parses that file to get the package header declared therein.
