ncverilog sdf
How can i annotate SDF file as Using NC-verilog.
As I use the following words in testbench:
$sdf_annotate ("sdffile.sdf", "module_name", ,"sdffile.log");
I find Nc-verilog can't recognize this mode.because there is no error report when I use an invalid sdf file.
I use another way to back annotate.The tool I use is "Virtuoso Schematic Composer Analysis Environment For NC-verilog Integration".I enable it from "Virtuoso Schematic Reading".After setting in the menu->setup->sdf delay annotate of this tool.a file sdf2sdf.log was created.there are many warnings in this log file.part of this was showed like:
simViewName = "schematic"
Hierarchy divider / will be mapped to .
WARNING - Instance does not have a mapped name
WARNING - Cannot find pinmap data for instance U98 (master ), pin N01.
WARNING - The verilog model is . Using original pin name for this pin.
WARNING - Cannot find pinmap data for instance dcon_7_reg (master ), pin H02.
WARNING - The verilog model is . Using original pin name for this pin.
WARNING - Cannot find pinmap data for instance databus_tri\[7\] (master ), pin N01.

in the end of the file report like this:
SDF name mapping completed successfully
Who can tell me how i can back annotate sdf file in NC-verilog?
