Name Description
[-strip_path] Specifies the name of the instance of the current design as it appears in the SAIF file
[-no_strip] Do not strip first two levels of hierarchy from SAIF file
[-out_file] Specifies the name of the output file that contains nets that could not be matched

Description

Reads a Switching Activity Interchange Format (SAIF) file for use during power analysis by the report_power command, or power optimization by power_opt_design. The read_saif command will annotate the design nodes with activity from the SAIF file and estimate power appropriately.

Running report_power or power_opt_design after reading the SAIF file will use the activity rates from the specified file during optimization and analysis.

Arguments

-strip_path <arg> - (Optional) Strip the specified instance path prefix from elements in the SAIF file to allow them to be mapped properly to instances in the current design.

Tip: The instance path specified should not begin with a '/'. The read_saif parser looks for design net names, which do not have a leading '/'.

-no_strip - (Optional) Do not strip first two levels of hierarchy from the SAIF file.

-out_file <arg> - (Optional) The name of an output file where unmatched nets and other messages are reported. This file is created during the import of the SAIF file. If the -out_file option is not specified, the information is not saved to a file.

Note: If the path is not specified as part of the file name, the tool will write the specified file to the current working directory, or the directory from which the tool was launched.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<file> - (Required) The name of the SAIF file to read.

Note: If the path is not specified as part of the file name, the tool will search for the specified file in the current working directory and then in the directory from which the tool was launched.

Examples

The following example: 

read_saif -strip_path design/top/F1 C:/Data/design1.saif
