第一次做DFT,遇到了一个clock问题和RAM的问题,,,不知道怎么分析,,希望路过大神指点一下。
aRst ( Warning: Clock aRst used as data is different than capture clock clk_24M for inputs CK/D of stable DFF (EDC_insert/state_reg_3_).
clk_24to96/FIFO_26_16_SRAM_26x16 (Cell clk_24to96/FIFO_26_16_SRAM_26x16 (SRAM_26x16) is unknown (black box) because functionality for output pin DAOUT[0] is bad or incomplete.
我还想问一下,设计中报出的这样的一个warning,是不是就说明这个端口不能够功能复用了?
Warning: Port 'aRst' cannot be used as a scan port. It has been previously inferred as an asynchronous signal
