做了几个实验,进一步总结了一下关于clock network的TR/SP的propagated数据计算方式,测试数据如下: 关键属性: toggle_rate pin/net double A static_probability pin/net float A switching_power_derate_factor clock network propagated方式设置(through_mode/Zero-Delay-Simulation): set_power_analysis_options -throug...
假设时钟周期为10ns,U1、U2和触发器的延时分别为2ns,1ns,1ns。从输入端口clk到触发器的CK端latency为1.5ns。setup要求为0ns。 create_clock -period 10 [get_ports clk] set_annotated_delay 2 -cell -from U1/A -to U1/Y set_annotated_delay 1 -cell -from U2/A -to U2/Y set_annotated_delay ...
1、首先需要打开clocknetworkdelay软件网站。2、其次进入该网站内部，找到设置。3、最后只要是在设置里面进行设置自己想要的即可。
网络时钟网络延时 网络释义 1. 时钟网络延时 看到了吧,这时候的锁存沿(latch clock,即SDRAMCLK)的时钟网络延时(Clock network delay)就是图1中看到的1.567ns … blog.chinaaet.com|基于6个网页
而在CTS之后,每一个cell其实都有了真实的RC值,这个时候需要通过clock propagate的方式,对每一级的transition进行传递和计算。这个时候set_clock_transition会无效。相关命令如下所示。它会导致整个CLK1的network都按照propagated的方式进行delay和trans的计算。
Clock synchronization for network measurements with clock resets Several algorithms are provided to estimate and remove relative clock skews from delay measurements based on the computation of convex hulls. The algorithms are linear in the number of measurement points for the case with no clock resets...

i am learning timequest and sdc, but now i have some confusion with the difference of the clock network delay between Timequest report and chip
假设我们对于RegB 用的virtual clock(如示例),在CTS之后,就可以对VCLK加上latency:set_clock_latency -clock VCLK $clock_network_delay。 而对于real clock,在CTS之后,都要由ideal clock设为propgated clock(set_propagated_clock), 这样,对于real clck,是不能够用set_clock_latency设置clock network delay的。
