WebbSDC是术语“Synopsys公司设计约束（Synopsys Design Constraints）”，用于描述对时序、功率和面积的设计要求，是EDA工具中用于综合，静态时序分析和布局布线最常用的格式。 时序约束的出现是主要应对指定HDL中无法捕获的涉及特性，同时也用于驱动综合。 他们的是目标是为综合工具提供指导，以优化设计的面积与性能曲线。 后来渐渐的PrimeTime … WebbHowever, this is a Timing Analyzer-only extension and makes the SDC syntax non-standard. The -waveform option specifies the rising and falling edges (duty cycle) of the clock, and … Webb21 dec. 2010 · The design is described as follows. --- The FPGA provide a reference clk (125Mhz) to a SERDES chip. --- The SERDES chip ouputs a clk (62.5Mhz) and a databus (10-bit) to the FPGA. --- The 10-bit data should be sampled at both the rising edge and falling edge of the 62.5Mhz clk in the FPGA. jared\\u0027s paint and body groves tx
