I have been looking into VHDL as a 'soft' language, my background is embedded software and my experience/knowledge of vhdl is limited but I am familiar with the basics. I would like to begin construction of a vhdl parse tool but I am unable to find any really usefull information on a standard output for a vhdl parser. I have the language reference manual and have the bnf (syntatic description) which would allow me to get as far as tokenising an input file and applying rules but ultimately I should be able to feed the output of the parse into a synthesis tool.. (?) I have found some information refering to vif (vhdl intermediate format) which I believe is proprietry (please correct me if I am wrong) but there must be a standardised interface established ISO,ANSI......GNU? If anyone has any information or pointers I would like to hear from you. Thanks all Ben -------------- next part -------------- An HTML attachment was scrubbed...

I think what you want is a netlist. -----Original Message----- From: cores-bounces at opencores.org on behalf of Hotmail Sent: Wed 6/23/2004 2:13 PM To: cores at opencores.org Cc: Subject: [oc] Help Wanted - VHDL Parser Construction I have been looking into VHDL as a 'soft' language, my background is embedded software and my experience/knowledge of vhdl is limited but I am familiar with the basics.

You should look at ghdl.free.fr
