Any example of pt2tmax.tcl?

[wakki1187]

Hi..
Has anyone ever use the command:

source pt2tmax.tcl
write_delay_paths -max_paths (value) <output filename>

?

I read in tmax user guide it is to import delay paths generated from PrimeTime. but when I used it, the file created only contain the version number of pt2tmax script.

How can I import the delay paths to tetramax?

have u read manpage or help of write_delay_paths? I doubt your usage is not very proper. -slack may help.

Extracting Slack Data from PrimeTime
TetraMAX utilizes a specific set of timing data extracted from PrimeTime. To obtain this
information, you need to call a function that extracts slack data for all pins from PrimeTime.
This function, write_timing_slacks, is defined in the pt2tmax.tcl script that is included
in the TetraMAX release tree. As shown in the syntax description below for
write_timing_slacks, you need to specify a name for the output file to which the slack
information is written.
Syntax:
write_timing_slacks <output_filename>
Understanding the Slack Data File Format
The script example in the previous section creates a slack data file that TetraMAX can read
and correctly parse the data. The following example shows a typical slack data file with
proper formatting:
SPARE10/VLO1X/Z INFINITY INFINITY
U54/A 21 INFINITY
U73/A 22.286619 23.575638
U113/A1 -23.400898 -21.773178
U113/B1 22.020908 0
U113/B2 23.755539 INFINITY
U113/C 22.045767 21.629681
U_IO_BUF/U_D0/A 1.552831 0.214887
U_IO_BUF/U_D0/EN 3.700592 3.938488
Note the following:
• The first column is the node on which the slack is applied.
• The middle column is the rising transition slack.
• The last column is the falling transition slack.
