Error: couldn't read file "<variation_name>_phy_ddr_timing.tcl": no such file or directory while executing "source "<variation_name>_phy_ddr_timing.tcl" (file "<sub-directory>/<variation_name>_phy_ddr_timing.sdc" line 33)

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

In the Quartus® II software version 9.1 and 9.1SP1, the sdc script is unable to source the "<variation_name>_phy_ddr_timing.tcl" file during compilation if the IP files for ALTMEMPHY or High Performance Controllers for DDR2 and DDR3 SDRAM interfaces in Arria® II GX and Stratix® IV devices are not located in the project top level directory.

 

The workaround is to place a copy of the <variation_name>_phy_ddr_timing.tcl in the top level project directory.

 

For the TimeQuest Report DDR command to work, also place a copy of these tcl files in the top level project directory:

 

1. <variation_name>_phy_ddr_pins.tcl

2. <variation_name>_phy_report_timing.tcl

3. <variation_name>_ phy_report_timing_core.tcl

 

If you re-generate the IP, you need to copy over the tcl files again. This issue is expected to be fixed in a later version of Quartus II software.
