What is VPWL in pspice?

Solution. The piece-wise linear voltage sources allow you to describe a transient voltage waveform by connecting time-voltage pairs, which you define. The following are schematic parts that can be used, along with their property definitions: Name: VPWL. Use: Piece-wise linear voltage source.

How do you use VPWL?

To add a PWL function to a voltage or current source:

  1. Right-click on the symbol in the schematic editor.
  2. Click Advanced.
  3. Select either PWL(t1, v1, t2, v2…) or PWL File:
  4. Depending on your choice in step 3, either enter the PWL values or choose a file.

How do I get VCC in pspice?

Select Place > Power and scroll down to the VCC_CIRCLE symbol and in the Name: box, change the name to VCC and click on OK. Repeat for the VSS symbol.

What is PWL file in cadence?

• PWL files are text files. with rows of time/value. pairs. – ‘Time’ and ‘Value’ are. separated by a space.

How do I get voltage source in LTspice?

Add other components – Press “F2” or click the component button to insert a component. A “Select Component Symbol” window will open. Take a minute to browse through the list of available components. Note that sources are labeled as “current” and “voltage”.

What is hspice simulation?

HSPICE is an analog circuit simulator (similar to Berkeley’s SPICE-3) capable of performing transient, steady state, and frequency domain analyses. Existing SPICE decks created for SPICE- 3 can be easily modified to run under HSPICE, or can be rewritten to take advantage of features not available in SPICE-3.

What is VCC used for?

VCC is the power input of a device. It may be positive or negative with respect to GND. When the only positive power supply is used then VSS (Voltage Source Supply) means ground or zero. The Intel 8085 Microprocessor needs a power supply of +5 V DC for its working.

What is the full form of PSpice?

PSpice is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.

How do you repeat a PWL in LTspice?

If you want to repeat the above waveform, LTspice allows you to edit the PWL text. To repeat the above waveform 5 times, right click over the PWL text and alter as shown in FIG 6. LTspice also allows PWL waveforms to be read from a file.

What is pulse train generator?

A pulse train is a series of generated pulses. The pulses in a pulse train can be identical or unique. The Tabor family of Arbitrary Waveform Generators (AWGs) is designed for easy programming of pulse trains. This document will quickly guide you through the process of pulse train generation.

What is BV in LTspice?

A behavioural voltage source outputs a voltage according to any number of circuit parameters and it can be used to unleash the real mathematical power of LTspice.

Is Hspice free?

HSPICE has its own GUI (graphic user int erface) for waveform viewing, but it is unfortunately a badly design interface. It runs on UNIX. Due to the fact that HSPICE is well recognized and trusted by the industry, simulation res ults of it is usually more persuasive. And it is certainly NOT free.

What is the difference between Hspice and PSpice?

difference between pspice and hspice PSpice comes with a schematic capture program and does some things automatically. It is good for casual and new users. HSpice has a wider range of user selectable options but therefore requires more user skill.

What is PWM generator?

Description. The PWM Generator block implements a PWM generator. The pulse width modulation technique controls power transfer from one electrical component to another by quickly switching between full power transfer and no power transfer.

Is VCC a 5V?

Vcc is the DIP package supply, it should be 5V, whatever the source, but boards might range from 2.7V to 5.5V depending upon design and that datasheet.
