Static Resistor Check (static_resistor)

Spectre Syntax

title static_resistor type=[range|distr|print] rmin=<value> rmax=<value> error_limit=<value>

SPICE Syntax

.cck title static_resistor type=[range|distr|print] rmin=<value> rmax=<value> error_limit=<value>

Description

Reports all resistors within or outside the range rmin and rmax. Moreover, it also generates a distribution list of all resistors in the circuit.

If the parameter type is set to range, then all resistors outside the range of rmin and rmax will be reported.

If the parameter type is set to print, then all resistors between rmin and rmax will be reported. The resistor names can be sorted by clicking the Device name header.

If the parameter type is set to distr then a distribution report will be generated for all resistors. There are 12 bins that are:

-Inf - 0, 0 - 1m, 1m - 10m, 10m - 0.1, 0.1 - 1, 1 - 10, 10 - 100, 100 - 1k, 1k - 10k, 10k - 100k, 100k - 1Meg, and 1Meg - Inf

However, if two or more consecutive bins are empty then they will merge into one bin, reducing the number of bins. The parameters rmin, rmax and error_limit are ignored when the parameter type is set to distr.

The results are written to a file with the extension static.xml, which can be viewed with a Web browser.

Arguments

type=range|distr|print	Type of report requested.
rmin	Lower bound of resistor value to be reported. Default is -1000G Ohm.
rmax	Upper bound of resistor value to be reported. Default is 1000G Ohm.
error_limit	Maximum number of errors to be reported when type=print or type=range. Default is 10000.

Example

Spectre Syntax

chk1 static_resistor type=distr

SPICE Syntax

.cck chk1 static_resistor type=distr

The simulator generates a resistor value distribution report, as shown below.
