*******************************************************************************************
Key features & updates of DSIM 2021b include:
New superfast AC Sweep
AC analysis is often a process that entails long simulation times, especially for large and complex systems.
DSIM’s brand-new AC Sweep support speeds up this process to a fraction of the time.
Switching transient simulation for the entire circuit
Previously, DSIM analyzed the switching transient of a converter with the transient confined within the converter for maximum speed performance.
Now, DSIM offers the new option of simulating the switching transient together with the external circuit for maximum accuracy. With this feature, it is also possible to perform EMI simulations.
DLL Support
DSIM now supports DLL blocks with 1, 3, 6, 12, 20, and 25 inputs as well as the general DLL block; so, you can use your custom c code.
Automatic Conversion of Comparator-Based PWM
When comparator-based PWM circuits are built, the DSIM solver will automatically convert the circuits to carrier PWM blocks. With this functionality, many existing examples in the PSIM example folder, or built by PSIM users before, can be directly solved by DSIM without extra effort.
Automatic Discretization of S-Domain Blocks
DSIM V2021b now automatically discretizes s-domain blocks. The discretization frequency is dependent on the maximum frequency inside the circuit, and a minimum frequency of 100 kHz will be used. The continuous transfer functions are discretized by bilinear transformation.
New Elements
DSIM V2021b supports over 50 new elements.

20 new examples are added to the DSIM Example Library.
