Virtual prototyping of mixed mode analog and digital circuits in power conversion applications is now practical regardless of the level of digital content.

• SIMPLIS allows designers of digitally controlled power supplies to effectively explore the interaction between increasingly complex digital control schemes and the resulting performance of the complete power supply system.
• The new higher level digital functions remove the need to build these functions up from the gate level - effectively reducing the circuit size and the complexity of the simulation.
• SIMPLIS also improves the simulation speed of power supply systems with significant digital content describing supervisory and protection circuits.

The Advanced Digital Library provides a wide variety of new digital functions to simplify your simulation efforts. In addition to the basic logic gates that have long been included in the SIMPLIS engine, the library now includes:

• Adders
• Subtracters
• Multipliers
• Comparators
• Counters
• ADCs
• Expanded library of flip-flops and latches

All new logic functions in the Advanced Digital library have improved characteristics including:

• Inertial delay on inputs. (Input glitches narrower than the specified delay are effectively ignored rather than being propagated through the device.)
• Finite delay in all Advanced Digital devices. (This eliminates problems associated with the classic SIMPLIS logic gate's ability to instantaneously switch state with zero delay.)

Simulation speed is improved 10-20x for classic digital gate simulation compared to earlier versions of SIMPLIS.

The enhanced SIMPLIS digital simulator:

• allows the simulation of digital circuits to go faster
• reduces the numerical complexity of the power supply simulation.

Additionally, the digital clock frequency can now be much higher than the switching frequency of power supply. This allows SIMPLIS simulation times of power supplies with digital control schemes to be comparable to those with equivalent analog control circuits.
