FPGA:

What's it do?

When using an FPGA, one must generate a mapping between internal signals and external pins. This tool is helpful in creating a mapping file for the B5-X from BurchED.biz. The way you want to use this to enter the names of signal vectors and the physical location of the various connectors. The web page below is broken up into different 'parts'. Each part corresponds to a part you might have purchased from www.burched.biz. When asked to which connector a device is connected, your options are A, B, C, D, E, F, G, or H If you leave a connector field blank, all other fields will be skipped and no .ucf entries will be generated for that entire part. When asked for a vector for a series of signals, keep in mind that this code assumes that your vectors are 0 based. And, the 16 bit interfaces (LED's and Switches) are expected to be used as one continuous vector. However, you can change the range of a vector by using the syntax: vector<start-end> The start and end regions are decimal numbers. Also, some signals are independent (not grouped). Examples include the Chip Select for the SRAM interface, and the keyboard data signal for the PC Peripherals interface. In these cases just put in the signal name that you use. For any signals that you don't use, just leave the fields blank. You don't have JavaScript enabled on your browser.
