With the correct tag this time... I've been searching the web for a free/low cost "'timing diagram' + editor" that can help me make timing diagrams for some simple MSI logic ccts. (counters, shift registers, basic logic, etc.) So far I haven't been able to find anything suitable. Everything that turns up is for VHDL of LSI ICs with requires building the MSI logic chips from scratch. (74HC166, '161, '595, '08, etc). Surely there is something out there that is simpler that VHDL yet more efficient than using graph paper and a ruler? Or am I not using the right search terms? Thanks in advance for any recommendations. Robert -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
