Can I read DFT clk mux and DFT clk chain Overview on EtoBox?
DFT clk mux and DFT clk chain Overview by Rohit Patel is a document available to read on EtoBox.
What is DFT clk mux and DFT clk chain Overview about?
The document describes the DFT_clk_mux and DFT_clk_chain components added by the DFT Compiler when clock control is enabled. DFT_clk_mux selects between fast and slow clock sources for scan shifting and capture based on control signals. DFT_clk_chain controls the capture pulses by loading a pattern into DFT_clk_mux during scan shifts. The components provide glitch-free clock switching for ATPG-specified capture sequences of up to 10 pulses from asynchronous clock domains.
