例如,当移位寄存器深度为4,-shreg_min_size为3,-no_srlextract被勾选,那么最终实现形式是4个触发器级联的形式,而非FF + LUT + FF的形式。 在SystemGenerator中,有两个模块Delay和Register,如下图所示。这两个模块是不同的。对于Delay延迟深度可设定,对于Register延迟深度就是1。 进一步,对于Delay的描述如下图...

This will generate a single inverter whose input is connected to the output, and it will oscillate unpredictably. I managed to generate a bitstream without problems using Vivado (on the latest dev-int branch, where both timers are implemented). So why does it fail on your machine ? Hmmmm. ...
