Fixed Bugs and Known Problems The MathWorks offers a user-searchable Bug Reports database so you can view Bug Reports. The development team updates this database at release time and as more information becomes available. Bug Reports include provisions for any known workarounds or file replacements. Information is available for bugs existing in or fixed in Release 14SP2 or later.

See also Summary New features and changes introduced in this version are: · "New Linear and Rotary Motors Defined in Terms of Flux " on page 3 · "New Potentiometer Block" on page 4 · "Initial Conditions Tab Added for Logic Blocks" on page 4 · "Changes in Block Parameterization" on page 4 · "New Demos" on page 5 · "Functions and Function Elements Being Removed " on page 6 New Linear and Rotary Motors Defined in Terms of Flux Two new blocks represent models of a motor or actuator defined in terms of magnetic flux: · FEM-Parameterized Linear Actuator block, located in the Translational Actuators library · FEM-Parameterized Rotary Actuator block, located in the Rotational Actuators library 3 SimElectronics® Release Notes New Potentiometer Block The new Potentiometer block, located in the Passive Devices library, represents a potentiometer, where the wiper position is controlled by the input physical signal. Initial Conditions Tab Added for Logic Blocks The dialog boxes of blocks in the Logic library now have an additional tab, Initial Conditions, which lets you specify the output initial state (low or high). See the respective block reference pages for details. Changes in Block Parameterization The ability to parameterize SimElectronics® blocks by importing circuit data from a SPICE netlist is no longer supported. See "Parameterizing Blocks" in the SimElectronics User's Guide for alternative ways of block parameterization. Additional related changes introduced in this version are: · "Changes to the SPICE-Compatible Blocks" on page 4 · "Changes to the Solar Cell Block" on page 5 · "Compatibility Considerations" on page 5 Changes to the SPICE-Compatible Blocks The SPICE-compatible blocks have been moved to the Additional Components library. They are organized in sublibraries according to function, for example, the SPICE-Compatible Sources library is now the Sources sublibrary of the Additional Components/SPICE-Compatible Components library. The Resistor block, renamed SPICE Resistor, and the Current-Controlled Switch and Voltage-Controlled Switch blocks have been moved to the Passive Devices sublibrary of the Additional Components/SPICE-Compatible Components library. Some of the blocks have been renamed so that their names start with the "SPICE" prefix. The following table lists the old and new block names. 4 Version 1. 4 (R2010a) SimElectronics® Software Old Name Diode (SPICE) NJFET NMOS NPN PJFET PMOS PNP Resistor New Name SPICE Diode SPICE NJFET SPICE NMOS SPICE NPN SPICE PJFET SPICE PMOS SPICE PNP SPICE Resistor There are no compatibility considerations as a result of renaming the SPICE-compatible blocks and moving them to the Additional Components library. Your existing models will be updated automatically when you open and save them in the new version. Changes to the Solar Cell Block In previous versions, the Solar Cell block had the option of using the SPICE Environment Parameters block to set temperature. This is removed in R2010a to eliminate dependency on the SPICE sublibrary. Also, the Solar Cell model now uses the regular Diode block (exponential diode) rather than the SPICE Diode block. Compatibility Considerations There is an insignificant change in results, of the order of 1e-12, in the Solar Cell block because of the diode replacement.
