The following steps should be followed to complete your simulation lab

  • Get all parts that you need for your lab
  • Lay-out the part as indicated on the Lab schematic
  • Connect the Wire for your circuit
  • Save your work
  • Enter all values that required in the Simulation Lab ( Value of the Component and Source )
  • Setup for your simulated program
  • Run Simulate
  • Collect the Data
  • Complete the Report

To simulate your circuit follows the following instruction step-by-step

  1. EXECUTE the Simulation Program

Double Click on schematic Icon from desktop Windows if you see it otherwise see your instructor for help

  1. Get PARTS for your circuit

a)From MicroSim Schematics Windows, Click Draw from the Bar Menu

b)Click Get New Part….

c)From Part Browser Basic Windows, move the scroll bar to the part that you want to get then click Place to place your part

d)Right click to release the part and ready for next part

e)Click Close to close Part Browser Basic Windows

f)NOTE: Get one part for each component, for example in your circuit needs 5 resistors but you get only one R then will be using COPY later to get more resistor.

  1. COPY the PART

a)Click on the part that you want to COPY that part should turns RED

b)Press CRTL+C to copy

c)Press CRTL+V to paste the part. Each press CRTL+Vwill paste out one part, if you want more keep press CRTL+V

d)If you want to copy another part then you should start over from step a)

  1. ROTATE the PART

a)Click on the part that you want to ROTATE that part should turns RED

b)Press CRTL+R to rotate the part

  1. MOVE the PART

a)Click on the part that you want to MOVE that part should turns RED

b)Keep hold the mouse and move

c)Release the mouse

d)To Change the VALUE or Name of the part, Click on the value or name of the part, then change value or name of part

  1. Connect WIRE

a)From MicroSim Schematics Windows, Click Wire from the Draw drop-down Menu

b)Now the cursor turns out to be a pencil, Click at the point you want to make the connection then move it to the destination point then Click again.

c)Right Click to release the wire

d)To draw another move the cursor to the other part then DOUBLE RIGHT Click to get a pencil then start from step b) to draw the wiring again.

  1. Change the VALUE or NAME of the part

a)Double Click on the value or Name you want to change

b)Type a new value or new name

c)Click OK

  1. SAVE your work

a)From MicroSim Schematics Windows, Click Save As from the File drop-down Menu

b)Change location to save in Save in of the Save as Windows

c)Type the name to be saved in File name

d)Click Save

  1. ATTRIBUTE the Source

a)Double click on the source, it should turns RED

b)Enter required value then click Save Attr

c)Click OK if no more data to enter

  1. LABEL on the circuit

a)Double Click on the Wire you want to put the Label

b)Type in the Label then click OK

  1. SETUP THE SIMULATION

a)From MicroSim Schematics Windows, Click Setup… from the Analysis drop-down Menu

b)Click AC Sweep if you need the FREQUENCY DOMAIN ( For VAC Sources)

c)ClickDC Sweep for DC Variable Voltage or Current Sources

d)Click Transient if you need TIME DOMAIN ( For VSIN Source )

e)To setup follows step 12 or 13 or 14

f)Click Close to quit Analysis Window

g)NOTE: FOR DC CIRCUIT, IF YOU NEED ONLY DISPLAY THE VALUES OF DC VOLTAGE OR CURRENT THEN YOU DON’T NEED TO ENTER THE SETUP.

  1. Setup Continue on DC Sweep

a)From DC Sweep window

  • Type name of your source in the name box
  • Enter start value, end value and increment
  • Click OK
  1. Setup Continue on Transient

a)From Transient window

  • Enter Print Step and Final Time value
  • Click OK
  1. Setup Continue on AC Sweep

a)From AC Sweep and Noise Analysis window

  • Select Decade in AC Sweep Type box
  • Enter Start Freq and End Freq value
  • Click OK
  1. RUN SIMULATE

a)From MicroSim Schematics Windows, Click Simulate from the Analysis drop-down Menu

b)If you get any errors, correct the error and try Simulate again

c)If you doing ok then you should see the MicroSim Probe Window

  1. DISPLAY THE SIGNALS

a)From MicroSim Probe Window, Click Add from the Trace drop-down Menu

b)From Add Traces Window, unmarked Alias Name

c)From Add Traces Window, unmarked Currents if you don’t need the current

d)Click on Name of Voltage or Current you want to display then click OK

  1. COLLECT DATA

a)From MicroSim Probe Window, Click Cursor then Display from the Tools drop-down Menu

b)From MicroSim Probe Window, Click Cursor then Peak from the Tools drop-down Menu

c)From the Probe Cursor Window that will display the value of the item at the bottom of the Probe Window that is squared.

d)You can Click on the next item to get the value, make sure that item should be squared.

  1. CORECT THE SIMULATION ERRORS

a)From MicroSim Analysis, Click Examine output then Find ERROR from the File open.
