10. Adding a Board Library
This chapter describes how to create and build a custom board library to use inside
DSP Builder using built-in board components.
Each board library is defined by a XML board description file. This board description
file contains all the board components and their FPGA pin assignments.
DSP Builder supports the following development boards:
■
■
■
Cyclone III EP3C25 Starter board
Cyclone III EP3C120 board
Stratix III EP3SL150 board
f For information about these boards, refer to the DSP Builder Standard Blockset Libraries
section in volume 2 of the DSP Builder Handbook .
Creating a New Board Description
To add additional boards create new board description files. You only need to create a
board description file for each new board and run a MATLAB command to build it
into a DSP Builder Library. You can use the existing components or create your own
custom components.
Predefined Components
Predefined components are in the following folder:
< install dir >\quartus dsp_builder lib boardsupport components
There is a single XML file, < component_name >.component, that describes each
separate board component. This file defines its data type, direction, bus width, and
appearance. The file also contains a brief description of the component.
Component Types
There are three main types of component: single bit, fixed size bus, and selectable
single bit.
Single Bit Type
These components have a single bit with one FPGA pin assigned to each component.
The components are either inputs or outputs and you cannot change them. DSP
Builder offers the following single-bit predefined components:
■
■
■
■
■
Red and Green LEDs ( LED0 to LED17 and LEDG0 to LEDG8 )
Software switches ( SW0 to SW17 )
User push buttons (PB0 to PB3)
Reset push buttons ( IO_DEV_CLRn and USER_RESETN )
RS232 receive output and RS232 transmit input pins ( RS232Rout and RS232Tin )
