Example 18 - Functional but cryptic LFSR with nonblocking assignments 根据8.0段例子pipeline和10.0段例子LFSR,我们推荐对所有时序逻辑建模时使用非阻塞赋值(nonblocking assignment)。相似的分析也将显示出对latch建模时使用非阻塞赋值(nonblocking assignment)是最安全的。 #1: 当为时序逻辑建模,使用“非阻塞赋值”。 #...

组合逻辑路径是否需要插入pipeline,插入pipeline的位置需要注意。寄存器能少用就少用。 尽量不要用除法,首先除法器面积更大,除法也会有余数,余数是否需要保留就很麻烦。除以常数可以做成乘以定点常数的方法。 乘以常数用移位加,也可直接用*号。 例如a * 2‘d3,工具会帮你优化成 a << 2’d1 + a。甚至可能优化...
To describe two flip flops, you can write them as two separate Verilog always block. Let’s make it more interesting and put them in series into a two-stage pipeline. First the diagram, then the code. Two stage pipelined D flip flops ...
only one bit change at a time, but rest of the bits can be one or zero. Gray coding is popularly used when interfacing between two different clock domains. One more the example is that dual clock FIFO uses gray coding to avoid any mismatch between the post-layout simulation and pre-layou...
from theptp_td_phcmodule, and outputs both the 96-bit time-of-day timestamp and 64-bit relative timestamp in the destination clock domain, as well as both single-cycle and stretched PPS outputs. Also supports pipelining the serial data input, automatically compensating for the pipeline delay....
The module also contains a parametrizable output pipeline register to improve timing. The dma_if_mux module enables sharing the DMA interface across several DMA clients. This module handles the tags and select lines appropriately on both the descriptor and segmented memory interface for plug-and-...
