.options ltspicecompatibility=1
The above command enables some additional features in SIMetrix to provided greater LTspice® compatibility. The option implements these features:
- 'x' parameter for arbitrary sources. 'x' returns the voltage across the source
- Brace characters '{' and '}' found in arbitrary source expressions are substituted for '(' and ')'
- Unquoted parameter expressions are detected and quoted. E.g.
res_fac=1.5*1/(ai_fac*vds_fac)
is an error in SIMetrix because the expression starts with a digit but is not quoted. With the above option the expression will be detected and quoted automatically.
