Hi Michael, I am a little entry into ISS discussion. I had some minor comments: 1. Syntax for passing expression to a value shows up as follows R1 3 4 R='expression' Instead it should be R1 3 4 VALUE='expression' We have already specified R as spice designator so the value expression should need R again ///ly C1 3 4 VALUE='expression' 2. The document states (page8) that ISS does not include support for Indep sources; but we do need Vdc 3 4 0 kind of sources to short two points 3. We would also need expressions like R3 3 4 VALUE = 'I(VDC)' 4. Would keywords like TEMPER, TIME, FREQ be allowed in expressions for values or .params? 5. Are we allowed to have subcircuits with same name but nested in other top level subcircuits (scoped subcircuits)?
