---++ Current Focus

The committee currently has two areas of focus.

1. Previously we focused on developing a syntax and semantics for realtime sequences and properties that intermingle seamlessly with the current digital SVAs. We have encountered a number of problems with this work, and it has been deferred. Our current focus is on adding untimed LTL operators to SVAs. We are assuming that the SVAs will be checked by a digital simulator and as such can assume a discrete notion of time. In the future, we expect there will be a need for an assertion language that supports dense time, but we have chosen to focus on a simpler problem for the immediate future.

2. The addition of SVAs to Verilog-AMS. There is value from using assertions within Verilog-AMS models. We are exploring the necessary changes to Verilog-AMS to add the current
