In multisource CTS flow, the act of showing the number of drivers and its position which connects sinks in the design is very important. The arrangement of all the sinks can affect the QoR of the clock tree network structure.

WebAug 4, 2015 · Clock latency is the time taken by the clock to reach the sink pin from the clock source. It is divided into two parts – Clock Source Latency and Clock Network Latency. Clock Source Latency defines the delay between the clock waveform origin point to the definition point. WebIf your clock pin was placed in an odd corner during floorplanning, it could affect your clock tree. Look at the clock tree debugger in the GUI – Open the Clock Tree Debugger to see a tree of all clock gates, buffers, and sinks in your design.
