一些很好的FPGA设计实例

--\count:temp[3] is \count:temp[3]
--operation mode is normal

--\count:temp[2] is \count:temp[2]
--operation mode is normal

--clk is clk
--operation mode is input

clk = INPUT();


--digit[3] is digit[3]
--operation mode is output

digit[3] = OUTPUT(\count:temp[3]);

--digit[1] is digit[1]
--operation mode is output

--digit[0] is digit[0]
--operation mode is output

digit[0] = OUTPUT(\count:temp[0]);
