Static Timing Analysis (STA) is crucial for the timing analysis and final sign-off of modern digital IC designs. It helps front-end engineers in RTL design to take into account implementation limitations while designing logic or collaborating with other design blocks. On the other hand, STA is a mandatory skill for back-end engineers involved in physical implementation.Nowadays, with the exponential increase of ASICs’ complexity, it is crucial to have the appropriate methods to ensure an optimal design. The main objective is to give an introduction to the following independent approaches aimed at both design and verification processes. STA is a crucial methodology for timing analysis and final sign-off of modern digital IC designs. It helps front-end engineers in RTL design to take into account implementation limitations while designing logic or collaborating with other design blocks. On the other hand, STA is a mandatory skill for back-end engineers involved in physical implementation. PeakRDL tool is a toolchain that unifies many aspects of register automation using SystemRDL register description language. It allows the automatic generation of multiple accurate views, like synthesizable SystemVerilog RTL register blocks, dynamic HTML documentation, and UVM register model abstraction layer.
