Calculators And Tools

 
UltraCAD has written a variety of programs through the years and made them available to our customers. Most have been freeware, a few have required a license for purchase. Here is our current offering. Click on any calculator name to be taken to a page that describes it more fully.
   
These calculators are now available at no cost in a single downloadable package. To download your package, use this link:

www.ultracad.com/calculators/ucad_universal.zip
   
Calculators:  
All of these calculators are written in Microsoft Visual Basic. Some of these calculators may require supporting Microsoft files for operation. Usually they are already on your system. But if not, they are included in the download package and can be installed locally. Here is the installation Readme.txt file. BE SURE TO READ THE README.TXT FILE BEFORE INSTALLATION!!
 
 
UCAD_TTemp, PCB trace current/temperature Calculator

This calculator will calculate trace current/temperature parameters for virtually any size trace thickness and width. It will also calculate the trace internal temperature at any depth into the board. It is based on our new book "PCB Design Guide to Via and Trace Currents and Temperatures." Learn more about the calculator here.
 
UCADPCB4.3.exe, PCB Trace Calculator

This calculator is multifunctional! It can be used to calculate trace current/temperature effects, fusing current, trace resistance, and Ohm's Law calculations. It also allows adjustment for skin effect and skin depth and for the Proximity Effect. Version 4.3 is a significant upgrade based on the thermal simulation collaboration between Brooks and Dr. Adam. It provides a MUCH better fit to the IPC 2152 curves and provides significant insight and improvement to fusing calculations.

 
UCCALC.exe, Differential Impedance Transmission Line Calculator
  This calculator has been upgraded to Version 3.5. The upgrade now allows for input values significantly smaller than before. This is to accommodate users who found the original ranges too limiting.
 
UCADPDSI.exe, Power Distribution System Impedance Calculator

This calculator graphs an impedance function for a power distribution system on a PCB with an arbitrary number of capacitors with arbitrary associated lead and mounting inductance and arbitrary ESR. It is a significant upgrade of our previous ESR calculator, offering greater usability and OS compatibility.
 
UltraCAD's Electronic Impedance Tool:

This tool Helps calculate series and parallel impedance combinations of RLC components or impedance expressions in the form of R + jX or Z and angle Theta.
 
UltraCAD's Fourier Simulation Tool

Any (repetitive) waveform can be represented by a series of sine and/or cosine terms. This simulation tool explores this relationship with 4 waveforms: square, triangle, trapezoid and sawtooth.
UltraCAD's Calculator for Factorials, Permutations, and Combinations

This calculator will calculate factorials of any size (tested to 10,000,000,000!) and permutations and combinations, with or without regard for order, with or without replacement. It is accurate to about 12 figures and to any exponent of 10.
Ultra_CT.exe,  Crosstalk Coefficient Calculator
  This program will estimate a crosstalk coefficient between two parallel traces for a variety of different configurations. It has just been completely rewritten in VB.net 2008 with an improved GUI and so that it will run on all 64-bit Windows systems.
 
Wiregage3.exe, Wire Gauge Calculator
  This calculator converts between trace geometry (width and thickness) and equivalent AWG wire gauge. Version 3 has been rewritten in VB.net and runs on all Windows operating systems.
