各位高手,我使用的是altera的FPGA,然后设计中使用到了其中的PCIE IP,分配完管脚,综合没有问题。但是我想看一下PCIE 输出数据的管脚tx_out输出的数据。我将这个PIN信号加入到了singletap中,但是这样综合就会报下面的错误:
Error (15761): Output port dataout of the GXB transmitter channel PMA atom "transmit_pma0" must be connected to an output pin
Error (15761): Output port dataout of the GXB transmitter channel PMA atom "transmit_pma0" must be connected to an output pin
