Recreating a simple round padstack

Recreating a simple round padstack


This tutorial takes you through recreating a basic round thru-hole padstack.
1.    Open the new Padstack editor in Cadence:
2.    Select Thru-pin and circle on the start tab
3.    Enter the drill diameter
4.    Define the symbol that will be used to represent the drill hole:
5.    Define the Top and bottom layer inner, outer, and thermal geometry.  Since Peralta uses two-layer boards, geometry other than begin and end layers will be ignored.
6.    Define the soldermask geometry for the top and bottom layers
7.    Look through the summary page to ensure everything was entered correctly:
8.    Save to the custom symbols folder you created and included in your padpath.

Professional Distributors

These distributors are often used by professionals in industry, and provide the most complete selection of different parts.

Hobbyist and Surplus Distributors

These suppliers generally offer lower prices for components, but may not have data sheets for everything they sell. Do not buy parts without a data sheet.

Component Manufacturers

Here's a list of popular manufacturers and the types of components that they manufacture. Most of these companies offer free samples of parts to students working on design projects. Even if you're not sure you will use one of their parts, it's better to order samples anyway so that you have options if other plans do not work. Instructables also has a larger list of companies that offer free samples.
  • Analog Devices - analog switch ICs, data converters, amplifiers and linear, RF ICs, power management, MEMS and sensors, processors and DSP. Samples. 
  • Cypress - automotive, clocks and buffers, interfacing, lighting and power control, memory, programmable system-on-a-chip, touch sensing, USB, wireless. Samples. 
  • Maxim Integrated - amplifiers and comparators, analog switches and multiplexers, audio, automotive, clock, data converters, digital potentiometers, energy measurement and metering, filters, interfacing, LED and LCD lighting and displays, memory, micro controllers, optoelectronics, power and battery management, power line networking, protection and isolation, real-time clocks, security, sensors, storage, voltage supervisors, thermal management, video, voltage references, wireless. Samples. 
  • Microchip - microcontrollers, analog, interfacing, wireless, memory. Samples. 
  • NXP Semiconductors - microcontrollers, discrete and logic, near-field communication, interface and connectivity, media and audio processing, power management, radio frequency (RF), sensors, automotive. Samples. 
  • On Semiconductor - discrete, power management, logic, signal management 
  • Texas Instruments - amplifiers and linear, audio, automotive, clocks and timers, data converters, interfacing, logic, power management, digital signal processing (DSP), micro controllers, analog switches and multiplexers, temperature sensors, wireless. Samples.

Updating a Part in your Library

Updating a Part in your Library


Sometimes its necessary to make small changes to your parts as you learn more about them or need to define them better in order to identify more design mistakes during the design process. But it’s difficult to know how to propagate these changes to a given schematic. Let’s say you have made a part but forgot to add a part outline, but you already connected it up in your schematic.

Steps

  1. Go into the project explorer and navigate to the library in which your custom part is, and open it up.

  2. Make the necessary changes to your part and save using “ctrl+s” or by right clicking on the active tab and selecting “save”.

  3. Now you need to propagate your changes to your schematic. In the project explorer, go up to the affected schematic, expand until you find the design cache, identify the changed part, right click, and select "update cache". Select yes to all the dialog boxes and go back to your schematic.

  4. Your schematic is now updated. Make sure you fix any connection problems if you updated pin names or numbers.

Altering Trace Widths


Altering Trace Widths


Sometimes you need to globally change trace widths in your board after designing it. Instead of deleting them all and starting from scratch, you can select all the traces at once using the following steps:

1. Make sure you are in general edit mode by clicking on the icon highlighted in the top row of icons:


2. Right click in the design workspace, selecting “super filter --> Connect Line”


3. Drag a box around your entire design, selecting all connect lines


 4. Right click in the workspace and select “change width” in the resulting menu.



5. Hit enter and see the result:

6. Turn your super filter back off:
