Does anyone have information on the IEEE's proposed standard logic
value package? I have heard that IEEE and EIA are working on
standards. I would like to get a hold of the IEEE package if it is
available.

I haven't heard of an IEEE package, but the IEEE WAVES (Waveform And Vector Exchange Specification) standardization group is distributing a set of WAVES packages for ballotting. I don't know if this is what you are looking for, so the info is brief: A package called WAVES_SYSTEM allows you to represent almost all logic states currently used by simulators and testers. The purpose of this is to allow you to represent the logic values used by your simulator (or tester) accurately, and transport them correctly to another simulator or tester. The structure is not simple, but it allows you to represent more exotic logic states (e.g. 'valid' = logic 0 and logic 1, but not midband). Documentation is available in the form of IEEE WAVES ballotting documents. Hope this helps, Frances (koo@tcville.hac.com)
