9.1i Timing Analyzer - I cannot perform crossprobing to Synplify Pro 8.6.1 from Timing Analyzer

Description

I followed (Xilinx XAPP406) to set the environment variable and opened the Technology view in Synplify Pro8.6.1. However, I cannot find the option <External Cross Probing Engaged> in Synplify Pro.

When I try to perform crossprobing, the following warning message occurs in the console:

"WARNING:InterToolCommunication:14 - In trying to start the Synplicity Cross Probing system, the following was returned: "couldn't open socket: connection refused" Synplicity Cross Probing will not be enabled."

Solution

Synplicity no longer supports crossprobing from Timing Analyzer since Synplify Pro 8.1.

However, you can work around this issue as follows:

1. Save the timing report as <design_file>.twr.

2. Open the *.twr file in Synplify Pro.

3. Open the Technology Hierarchical/Flattened view in Synplify Pro.

4. Highlight one path name in the *.twr, and click on the shortcut <Filter on Selected Gates>. A new technology view opens and this path is shown.

See (Xilinx Answer 11247) for more information.
