STMicroelectronics Models
What Does Eldo-ST Mode Change?
Reverses the order of MOS length and width specification for rare cases where only
values are specified without keywords W= and L=.
• .option ERRDEVDUPLI
Forces Eldo to stop the simulation and generate an error if there are duplicate instance
names. Default.
• .option STPROBEOP
Forces Eldo to generate the operating point file named probeop# instead of
.op#.
What Does Eldo-ST Mode Change?
When Eldo-ST is invoked, model levels are automatically changed to use Eldo-ST in exactly
the same way as ST-SPICE.
You can use standard Eldo levels in Eldo-ST by adding the following in the .MODEL card:
MODTYPE=ELDO
Specially tuned device models have been developed for use when simulating
STMicroelectronics designs. These STMicroelectronics models are available within the
standard version of Eldo.
A special version of Eldo is also available which has been developed for use within the
STMicroelectronics design kit. This version is identical to the standard version in every respect
except that the STMicroelectronics device models occupy different levels within the lists of
available device models.
Option OPTYP
When Eldo-ST is invoked, an additional control of Operating Point information is available.
• .OPTION OPTYP=2
Can be specified only when either the -stver argument or the STVER option are set.
Used to print the reduced operating point information for the MOSFET models (see the
SPICE documentation for more details). Otherwise equivalent to optyp=1. This can be
used with UDM and BSIM4 models.
Table E-1 lists the character string displayed in the Operating Point table for the different optyp
values. Elements on the same line are synonymous: that is, the same value is printed if optyp
changes.
