π To create a TCL script for extracting the path attributes for provided paths in Static Timing Analysis (STA), you can use the following approach.
π Script Overview:
The script will extract various attributes of a timing path, such as its delay, slack, endpoint, startpoint, and more. Here's an example of how such a script might look:
# Script to find STA path attributes
# Ensure that the design is already loaded and STA is set up
# Define the path of interest
set start_point "<start_point_name>"
set end_point "<end_point_name>"
# Report the path
report_timing -from $start_point -to $end_point
# Extracting various attributes of the path
# Note: The specific commands and attributes you can extract will depend on your EDA tool
set path_delay [get_attribute [get_timing_paths -from $start_point -to $end_point] "path_delay"]
set path_slack [get_attribute [get_timing_paths -from $start_point -to $end_point] "path_slack"]
# Add more attributes as required
# Print the attributes
puts "Path Delay: $path_delay"
puts "Path Slack: $path_slack"
# Print other attributes
π Customization Note:
Remember to tailor the script to your specific design and tooling environment. The commands might vary based on your tool's version and functionality.
