**BUG** Concise problem statement: If the Model attribute for QXTAL1 is edited from: `XTALfast` to: `XTALnofast` then the sim does not run and this error is reported: `Error: unknown subckt: xqxtal1 in out xtalnofast` The netlist shows that the _s% argument that is correctly picked up for the XTALfast subckt is not picked up for the XTALnofast subckt even though the syntax of the two subckts seems to be the same. Steps to reproduce bug: 1. Run the sim as is with the Model attribute for QXTAL1 as `XTALfast`: it should run OK; 2. Edit the Model attribute for QXTAL1 to `XTALnofast then run the sim again; Results: `Error: unknown subckt: xqxtal1 in out xtalnofast` Expected results: Sim should run normally.
