PSpice User Guide Monte Carlo and sensitivity (worst-case) analyses October 2019 578 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. To assign 2% device and 10% lot tolerances to the resistance multiplier for R1 1. Select R1. 2. From the Edit menu, choose PSpice Model. Capture searches the libraries for the Rbreak model definition and makes a copy to create an instance model. 3. To change the instance model name from Rbreak to Rmonte1, do the following: a. In the Model Text frame, double-click Rbreak. b. Type RMonte1. 4. To add a 2% device tolerance and a 10% lot tolerance to the resistance multiplier, do the following: a. Add the following to the .MODEL statement (after R=1): DEV=2% LOT=10% The model editing window should look something like Figure 13-5 on page 579. 1. From the File menu, choose Save. By default, Capture saves the RMonte1 .MODEL definition to the DESIGN_NAME.LIB library, which is PSENSOR.LIB. Capture also automatically configures the library for local use. To find out more about adding model libraries to the configuration, see Configuring model libraries on page 244. To have resistors R2 and R4 use the same tolerances as R1 1. In Capture's schematic page editor, select R2 and R4. 2. From the Edit menu, select Properties. 3. In the R2 row, click in the cell under the Implementation column and type RMonte1. 4. In the R4 row, click in the cell under the Implementation column and type RMonte1. To assign 5% device tolerance to the resistance multiplier for R3
