| Excel spreadsheet to calculate the impedance of milled circuit board traces. (Also known as "coplanar waveguides with ground"). This is needed for high-speed board development using "circuit board milling machines" such as those made by IBC, T-Tech, LPKF, and others. | |
| cfpod.doc | Design and Construction of a High-Speed BDM Pod for ColdFire
CPUs. This document contains information on how to modify P&E BDM pods for
higher-speed operation. It also contains a reference design of a pod that is
software compatible with the P&E version, but is built from the ground up for
high-speed operation. This document is in Microsoft WORD format. (Size, approx. 700K bytes.) |
| bdmcf.txt | PALASM source code for P&E BDM Pod (For GAL16LV8C) NOTE: you must rename this file to "bdmcf.pdf" before compiling. The file has to be listed here as a ".txt" file, because using a ".pdf" extension sometimes causes web browsers to think this is a "postscript" or Adobe Acrobat file, which will corrupt the download. So, download as a ".txt" file, then rename before compiling. |
| pems.txt | JEDEC programming file for P&E BDM Pod (For GAL 16LV8C) NOTE: you must have a "pems.jed" file to program a GAL directly. Unfortunately, ".jed" files have non-printable characters in them, that will not allow them to be downloaded through most web browsers. This file here is the "printable text" of the programming file. If you need the download image, please e-mail us, and we will send you the file directly. (It seems to go through e-mail just fine.) Ask for file name "P_E_MS.JED". |
| xtime.doc | Introduction to high-speed timing analysis for 54MHz. 5206e ColdFire CPUs. This is intended for senior design engineers. It can also be used by engineering managers as a "checklist" to see if design work done by their engineers (or consulting engineers) is thouough enough to assure reliable system operation. |
