Mr. Google did not find this article/book (I don't know what it is). Mr. Amazon did not find this article/book (same as before...). It is mentioned in the vmkr documentation by Bell-Northern Research VHDL Group (http://www.pldworld.com/_hdl/1/tech-www.informatik.uni-hamburg.de/vhdl/tools/vmkr/doc/vmkr.doc.ps) but no other references found. Does anyone know where I can find this article/book? As a parting note, does anyone have any suggestion/recommendation on the usage of vmkr?
