Example: 

 

Click on the Schematics icon on Design Manager to open MicroSim Schematics.           

Select File/New or Click on the new file icon to create new file. 

Select Draw/Get New Part and select uA741, C, R, VDC, VSRC, GND_ANALOG. 

Double-click on the attribute value to change the values of a component. 

Select Draw/Wire and to connect the component. 

Select File/Save to save your file. 

Double-click VSRC (V3) to change AC to 1. 

Select Analysis/Setup to setup analysis. And select Bias Point Detail. 

After simulation, the DC values of voltage and current can be displayed using these functions.

DC Sweep

Select Analysis/Setup to setup analysis. And select DC Sweep.

Change Name to V3,

Change Start, End and Increment Value to –10, +10 and 0.1.

In order to simulate the circuit with the DC input voltage from -10 Volts to 10 Volts with a voltage increment of 0.1 Volts.

Select Analysis/Simulate [F11] to run simulation.

MicroSim Probe Window will automatically display.

Select Trace/Add in MicroSim Probe.

Select V(U1:OUT) to add the output voltage of the Operational Amplifier.

Select V(3:+) to add the positive terminal of the input source.

AC Sweep

Select Analysis/Setup to setup analysis. And select AC Sweep.

Only V3 is AC source. AC sweep is analysis from V3.

Change type to Decade

Change Pts/Decade, Start Freq and End Freq to 10, 10 and 100K.

The simulation will decade form with 10 points per decade with the frequency of the AC source swept from 10 Hz to 100 kHz.

Select Analysis/Simulate [F11] to run simulation.

MicroSim Probe Window will automatically display.

Select Trace/Add in MicroSim Probe.

Select DB( ) from function or macro window and then select V(U1:OUT).

Transient

For a transient type analysis, one of possible input source is VPWL (Piecewise Linear Voltage Source).

Select Draw/Get New Part and select VPWL.

Double-click VPWL(V3).

Change DC to 0, change AC to 0, and then change

T1 = 0m           V1 = 0v
T2 = 0.1m        V2 = 1v
T3 = 5.0m         V3 = 1v
T4 = 5.1m         V4 = 0v
T5 = 7.0m         V5 = 0v
T6 = 7.1m         V6 = -2v
T7 = 9.0m         V7 = -2v
T8 = 9.1m         V8 = 0v

Select Analysis/Setup to setup analysis. And select Transient.

Change Print Step and Final Time to 10ns and 10ms.

Select Analysis/Simulate [F11] to run simulation.

MicroSim Probe Window will automatically display.

Select Trace/Add in MicroSim Probe.

Select V(U1:OUT) and V(V3:+).
