Control Statements
• Option statements:
• Paramset statement
• Save statement

• Assert statement
With the assert statement, you can set custom characterization checks to specify the safe
operating conditions for your circuit. The Spectre circuit simulator then issues messages
telling you when parameters move outside the safe operating area and, conversely, when
the parameters return to the safe area.
Using model types as a primitive with the assert statement like below is not yet
supported:
check assert primitive=bsim3v3 param=l min=10u max=100u
• Simple combinations of alter and set statements
• Include statement
Any include statement between corner markers {//corner to //endcorner} are commented
in the Eldo output, and included files in this area are converted in the /out_dir/corner/
directory. Note that corner and endcorner are case-insensitive.
o
included lang=eldo|spice|spectre
Specifying the statement included lang=eldo|spice|spectre instead of simulator lang
behaves exactly like simulator lang, but in addition forces included files (included
within included lang and end lang statements) to be in the same language as
specified after included lang=. This avoids any need to specify simulator
lang=eldo|spice|spectre at the beginning of the called files. It forces the language of
included files to be controlled by the parent file. Specify end lang=eldo|spice|spectre
to return the simulation language to the default one.
