Resistive Divider Circuit

Resistive divider circuit can alternatively be called as voltage divider circuit. Such a circuit is shown in the following figure: This circuit divides the input voltage Vin depending on the resistance values according to the following formula: Vout = Vin…

Resistive Divider Layout

Open the layout view of the Resistive_divider cell and then copy/paste (Ctrl+C/Ctrl+V) an additional resistor. Running a DRC (pressing F5) on the above layout results in the following error. By pressing > we see that there is too little space…

Resistive Divider Schematic

Before starting the schematic design let’s celebrate the fact that the most commonly used following shortcuts in our daily life are also valid for Electric VLSI. Now we would build a resistive divider circuit. Go to the schematic view of…

Setup of LTspice with Electric

LTspice is a free software which performs SPICE simulations for electronic circuits. We use LTspice for spice simulation of the circuit designed in Electric. Setting in Electric Following are the steps to be followed to set up LTspice with Electric:…

Checking ERC (Well Check)

This process checks the connection of the n-well and p-substrate. The C5 process used here is an n-well process. The p-type substrate is common to all NMOS devices and should be grounded. One of the electrical rule checks (ERCs) is…

Layout vs. Schematic (LVS)

Layout vs. Schematic (LVS) in Electric is checked using Network Consistency Checking (NCC) To check this, execute Tools –> NCC –> Schematic and Layout views of Cell in Current Window. You can run this command being in any design window (schematic…

Key Binding in Electric

Key Binding binds a key; when pressed will execute a command from the menu to which it is bound. You can bind a key to a command as below: Go to File -> Preferences –> Categories –> General –> Key…
