I make sometimes
excell based electronics calculators, to make my work easyer.You can download
them here.

In the webpage http://circuitcalculator.com/wordpress you can find more calculators, from other
people.

** Mostly the file links work only
with Internet Explorer !**

chronological order)

PCB Material Library 2007-2016
(constantly updated)

A lsit of available prepreg and core
materials with all important properties.

PCB Interconnect Timing Analysis
Calculator 2007-2010

With this tool, you can determine PCB design
rules or you can check if the already
designed system

meets the timing requirements, or not. Timing
analysis is very recommended for high-speed digital systems.

An earlier version is available here.

DC/DC Converter Power Dissipation
Calculator 2010

This is a
calculation-sheet file to be used in the free program the Smath Studio, to
calculate power dissipation

in the indusctor and the power switches in a
DC/DC converter. The program is available here.

Characteristic Impedance Calculator, based on
Simulated RLGC data 2009

If you want to
get an accurate frequency-dependent characteristic impedance of a transmission
line,

Then you can use
a general purpose 2D field solver, like the FEMM to simulate for RLGC
parameters.

If you have them,
you still need to get the impedance, so you can put them together here.

This calculator
also calculates frequency dependent dielectric constant, and the G parameter
from the others.

Dielectric Constant Frequency
Compensation Calculator 2009

Most of the PCB
trace impedance calculators dont take the signal frequency into account.

With this
calculator, you can fill this gap, by providing frequency-pre-compensated
dielectric constant to them.

QUCS Templates:

Power Integrity Simulation
Templates 2008 description

These are QUCS
(free) simulator schematics template files. It can help you in doing
macromodeling, simulation

and design of
system-level power distribution networks for CPU/FPGA core and IO power rails.

Additional tools
needed for creating models to be inserted into the template:

QUCS circuit
simulator with S-parameter support (freeware, open source)

SonnetLite
PCB 3D EM Simulator (freeware)

TNT MMTL trace
impedance field solver (freeware, with registration)

Updated QUCS
templates:

Updated PDN Template (v2)
2019

This new version
allows PDN impedance simulation and decoupling network design using measured
VRM model and simulated PCB power plane model.

High-Speed Channel Template
2019

This template
allows „channel simulation” using QUCS, for high-speed serial multi-gig SERDES
channels in decomposition analysis, by chaining S-parameter models and lossy
Tlines together.

PCB Interconnect Loss Budget
Calculator 2008

With this
calculator, you can make an estimation an the PCB interconnect loss budget for
your high-speed

serial
interconnections, like PCI-express, or SATA.

PCB Propagation speed
Compensation Calculator 2007

With this, you
can match trace lengths whose are on different layers. However, its recommended
to put all

Your signals what
you have to match, ont same structure layers.

DDR Memory bus Trace-Length
Calculator 2007

With this tool, you can calculate trace
lengths, adjustments for memory-interface PCB-design

PCB Layer-Stack Planning
Calculator (based on IPC equations) v1.0
2007

With this tool, you can try how your
controlled impedance traces will look like on a selected PCB stackup.

PCB permittivity/impedance Frequency-compensation
calculator 2007

If you work with high speed PCB design, with
this tool you can calculate or compensate the effect of the

Permittivity
variation over frequency.

Synchronous systems (SDRAM-DSP)
Timing spreadsheet 2006

With this tool, you can make a timing
analysis for an SDRAM memory and embedded processor based system.
