CTS 的全称是Clock Tree Synthesis,其目的是尽可能的使同一个时钟信号到达各个终端节点的时间相同。 CTS的实现办法最常见的是通过在时钟信号的各个分支上插入buffer或者inverter来balance时钟信号的延迟。 Nonstop pins are pins that would normally be considered endpoints of the clock tr ...
1. Introduction In this class, we will be using the VCS Tool suite from Synopsys. The primary tools we will use will be VCS (Verilog Compiler Simulator) and VirSim, an graphical user interface to VCS for debugging and viewing waveforms. These tools are currently available on the Sun ...
Design Compiler Tutorial Before running synthesis the tool environment file must be sourced. If you have not done this please go back to the environment setup page. All steps on this page may be completed from a telnet or ssh window. Create a .synopsys_dc.s ...
