21.Timing Analysis does not support the analysis of latches as synchronous elements for the currently selected device family 原因:用analyze_latches_as_synchronous_elements setting可以让Quaruts II来分析同步锁存,但目前的器件不支持这个特性 措施:无须理会。时序分析可能将锁存器分析成回路。但并不一定分析正...
题目:Build a counter that counts from 0 to 999, inclusive, with a period of 1000 cycles. The reset input is synchronous, and should reset the counter to 0. from hdlbits 白话:构建一个周期为1000的计数器,计数范围为0~999。复位方式为同步复位,复位值为0 这题非常简单,不赘述 答案不唯一: module...

fifo_counter写而未满时增加1,读而未空时减1。同时发生读写操作时,fifo_counter不变。 rd_ptr and wr_ptr are read andwrite pointers. Since we selected the bits in these registers same as addresswidth of buffer, when buffer overflows, values will overflow and become 0. ...
