Prime Time中的clock分析包括: 1)Multiple clocks,clock from port/pin,virtual clock. 2)Clock network delay and skew,clock latency----delay of the clock network relative to the source. clock skew-----variation of arrival time of clock at destination point. 3)G
Verilog 常见错误汇总 1.Found clock-sensitive change during active clock edge at time <time> on register "<name>" 原因:vector source file中时钟敏感信号(如:数据,允许端,清零,同步加载等)在时钟的边缘同时变化.而时钟敏感信号是不能在时钟边沿变化的.其后果为导致结果不正确. 措施:编辑vector source file 2.Verilog HD
STM32F4 SPI with DMA A few people have requested code, so I thought I’d post the code showing how I’ve configured my GPIO, timer, SPI, DMA and NVIC modules, along with some explanation of how the system works.Note that I’m using the STM32F4 Standard
