Description
IRACV201 is a Verilog code development tool including a rich
Verilog library and graphical user interface. The tool set is
designed to facilitate motion control algorithm development
including motion peripheral and communication modules.
Flexible configuration allows the user to quickly realize hardware
on an FPGA to achieve a high performance AC motor control
system.
