ECE65). • Frequency response • And more . With built-in mathematical functions, behavioral modeling, circuit optimization, and electromechanical co-simulation, the OrCAD PSpice environment goes far beyond general circuit simulation. as above, but with a VPULSE voltage source. It was developed as public domain software at the University of California and versions 2G6 (vanilla SPICE) and 3.0 are still used. Start F=10. • Frequency response • And more . (Fig. For this source the frequency in Hz is 2/(2π) = 1/π = 0.3183. Details of VPULSE are (see Figure 6): Apply. (Capture 메뉴) PSpice - New/Edit Simulation Profile을 클릭한 다음 Analysis type을 AC Sweep/Noise를 클릭하고 Start Frequency에는 해석 결과의 시작 주파수값을 입력(0을 입력하면 에러발생)하고, End Frequency에는 끝 주파수(예 100 Mega Hz를 입력 시 100meg를 입력)합니다. DC the DC component of the wave. as above, but with a VPULSE voltage source. Hi, Could anyone suggest a method that allows to change the frequency of VPULSE voltage source during a transient simulation? Browse Cadence PSpice Model Library. V1 = First Voltage V2 = Second Voltage TD = Initial Delay TR = Absolute Rise Time TF = Absolute Fall Time PW = Pulse Width PER = Period To simulate a step response, we use a VPULSE source set to V1=0V, V2=1V, TD=0, TR=1ps, TF=1ps, PW=1s, and . PSPICE Tutorial 2 Transient Analysis in PSPICE . ECE65). Cadence® PSpice technology offers more than 33,000 models covering various types of devices that are included in the PSpice software. In PSPICE, I had set the VPULSE's attribute as. The VOFF is set to zero. The device models and simulation algorithms in vanilla SPICE are .

VAMPL is the amplitude, and FREQ is the frequency of the sine wave). The Pulse Width has been set to 5u, the Period has been set to 20u. Bias Point The Bias Point analysis is the starting point for all analysis. In PSpice, make a Bode plot of the transfer function by conducting an AC sweep on the input voltage. PSPICE Tutorial - Purdue University In the ORCAD, use VPULSE as the Vs and set V1=5V, V2=-5V, TD=0, TR=0, TF=0, PER=1/FREQUENCY and PW=0.5*PER Use the following specifications while verifying the RC of Fig # in ORCAD C1 0.001 PSpice simulates the circuit, and calculates its electrical characteristics. The original circuit had a sinusoidal input 9 cos 2t. Figure 1 shows the PSPICE schematic for a circuit that was analyzed in class. Simulate again with Amp=2 and Freq=500 . Table of Contents Launch ADE L, repeat steps A to D in section 3 of Basic Design Flow except that there is no . radio-frequency systems and targeted IC designs. Figure 1. And Pspice is a Product of the OrCAD Corporation and the student version we are using is (e.g. In "Simulation. If a 5V amplitude signal is specified, then V1 = 5V and V2 = -5V. I need to set VPULSE for +-10mV, 50% duty cycle square wave at 128 kHz with rise time and fall time of 10 ns. V1 = First Voltage V2 = Second Voltage TD = Initial Delay TR = Absolute Rise Time TF = Absolute Fall Time PW = Pulse Width PER = Period To simulate a step response, we use a VPULSE source set to V1=0V, V2=1V, TD=0, TR=1ps, TF=1ps, PW=1s, and . About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators . For example: For a 1 kHz VSIN source, set TSTOP to 2 ms to simulate 2 cycles. Moved to PCB Routing & Schematic Layout software & Simulation. Note that the The values you type in for V1 and V2 will depend on the amplitude specified on the lab instructions. If a 5V amplitude signal is specified, then V1 = 5V and V2 = -5V. Change the PER and PW to a certain value at 160uS and then to another value at 220uS.) I want to know how values are assigned to VPULSE in PSPICE for a sweep wave generator? 2) For a square or triangular wave, use VPULSE (Set delay time, TD = 0, for simulations in . Also Pspice is a simulation program that models the behavior of a circuit. 1,281. In "Simulation. The simulation should be in Frequency domain. source, such as VPULSE .
