pspice tolerance a passed parameter - pcb design -

Declaring and using a global parameter To use a global parameter in your design you need to: • define the parameter using a PARAM part and • use the parameter in place of a literal value somewhere in your design 107 Pspug book Page 108 Tuesday May 16 2000 1:17 PM Chapter 3 Preparing a design for simulation To declare a global parameter PSpice Reference Guide Commands [tolerance specification] Appended to each parameter using the format: [DEV [trackdist] [%]] [LOT [trackdist] [%]] to specify an individual device (DEV) and the device lot (LOT) parameter value deviations The tolerance specification is used by the MC (Monte Carlo analysis) analysis only

Resistor Value

Morgan Jones in Valve Amplifiers (Fourth Edition) 2012 Preferred Values So far we have calculated resistor values and then picked the nearest preferred value These preferred values are derived from an exponential function so they are known as E series (E6 E12 E24 and E96) whose values are given in Appendix A Each series denotes the number of different values in a decade

It's time to continue my short series on simulation experiments In Part 1 and Part 2 I discussed the basics of simulation experiments and general features of Experiment Manager the SystemVision application for simplifying executing and managing simulation experiments In this post I'll use a simple motor driver example to illustrate the basics of Experiment Manager operation

2018-12-21You have placed components on the schematic maybe even fully wired compiled and taken the design to the board layout stage More than likely there will come a time when a change to a component is required - a new parameter added a change to a model link or maybe a change to a symbol or footprint at the graphical-level

2020-8-16Now one way to improve the tolerance is to choose tighter-tolerance resistors If more headroom is needed designers can choose 0 1% or 0 5% resistors even though they may cost a little bit more There is a power tip online where you can learn more about choosing resistors for DC/DC converter voltage dividers

Basics: Power dissipation and electronic components

An ever-present challenge in electronic circuit design is selecting suitable components that not only perform their intended task but also will survive under foreseeable operating conditions A big part of that process is making sure that your components will stay within their safe operating limits in terms of current voltage and power

The main purpose of CC circuits is to provide a low output resistance to connect to low resistance (impedance) loads Such as a speaker Now if you connect let's say an 8 ohm speaker to a CC circuit which has also approx 8ohm output dynamic resistance to get the maximum output power then a simple Thevenin model tells you the voltage gain will be 1/2

Integration with the PSpice A/D Simulator You can now simulate designs created in Concept HDL using the PSpice A/D Simulator PSpice A/D is a simulation program that models the behavior of a circuit PSpice A/D simulates analog-only mixed analog/digital and digital-only circuits

Cadence PCB Systems Division 13221 SW 68th Parkway Suite 200 By default any device which has a model parameter specifying either a DEV tolerance or a LOT tolerance is included in the analysis (Monte Carlo analysis) WCASE varies only one parameter per run This allows PSpice to calculate the sensitivity of the output waveform to

PCB Design: PSPICE tolerance a passed parameter PCB Design Forums how can I pass the value of the inductor for that particular monte carlo run into a parameter that is passed into a subcircuit For instance I would like to vary an inductor (nominal = 10uH) 10% For a particular monte carlo run lets assume it gets set to 10% or 11uH

2014-1-6Good design practice would dictate that the designer should make the PCB trace at least 27 mils wide if 1 oz copper is used If the designer is constrained such that they cannot accommodate 27-mil-wide PCB traces they should increase the copper weight if possible or just be aware that the trace will most likely fuse if the MOV fails short

Dennis Fitzpatrick in Analog Design and Simulation Using OrCAD Capture and PSpice (Second Edition) 2018 Abstract PSpice models can be created and edited in the PSpice Model Editor When users edit a PSpice part from Capture a copy of the PSpice model is created in a library file which will have the same name as the project

2020-8-18By definition a low-pass filter is a circuit offering easy passage to low-frequency signals and difficult passage to high-frequency signals There are two basic kinds of circuits capable of accomplishing this objective and many variations of each one: The inductive low-pass filter in (Figure below) and the capacitive low-pass filter in (Figure also below)
