[comp.lang.vhdl] Analog HDL

agw@foobar.mlb.semi.harris.com (Alan Whittaker) (03/14/91)

Is anyone out there still working on AHDL?  There was a lot of talk
about it at one time, but it seems to have died out a little.  I`m
specifically looking for any information on work on any standards
being developed for an AHDL or an analog package for VHDL.  Any pointers
to work being done to model analog behavior with VHDL or any other HDLs
would be appreciated, as would discussions of proposals to the 1992
restandardization committee on features in VHDL to support analog modeling.

Work is proceeding on the collection of analog requirements for VHDL
92.  Mark Brown (of IBM) is the head of that committee.  I will send
him Email requesting permission to post his own Email address to the
net.

The latest work that I know of being done concerning actually modeling
analog circuits in VHDL 87 is by Ted Cooley of Dartmouth College (New
Hampshire) and Don Hansen (Mississippi State).  Both are involved in
the Microwave Hardware Description Project (MHDL) currently underway.
MHDL is a separate project; its relationship remains somewhat unclear
(this relationship is the subject of a feasibility study being
performed by Intermetrics, Inc.).

I am reluctant to launch into great detail without knowing more
specifically your interest.  At your discretion, please post more
specific questions or send Email to the address below.  If there is
sufficient interest, I will prepare a general post on the MHDL
project.
