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
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
, 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
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:
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
