Units
Units are case-sensitive. Generally only units with useful conversions are defined. Unit tracking or aggregation is generally not desired. If no unit is defined, the default is assumed. The following is a list of standard units.
Length
Default is meter. Permissible units are:
m
mil, mils
in, inch
ft, foot, feet
mi, mile
Angle
Default is degrees. Permissible units are:
deg, degree, degrees
rad, radian, radians
Time
Default is seconds. Permissible units are:
day, dy, days
hour, hours, hr, hrs
min, minutes, minute
s, second, seconds
Percent
Permissible units are:
%
Log
Permissible units are:
dB: linear translation assumes "voltage" dB, e.g. -3dB is 0.7071 (convention for S-Parameters)
Metric
Default is no modifier. If the unit is not one of the above, then the first character in the unit will set the multiplier. Therefore 'nF', 'nH', 'n', and 'no_unit' are all equivalent to Mason (obviously the last one would cause confusing results for the unwary designer).
