Error: The dynamic chainout feature for fixed-point DSP is an advanced feature not supported in the current release. Disconnect the disable_chainout port and contact Altera for details.

Description

This error message will be seen during compilation when using the Primitive DSP Native Fixed Point DSP Agilex™ FPGA IP and the "Enable disable_chainout" option is enabled.

This problem only affects the Agilex™ 5 and Agilex™ 7 devices.

Resolution

To work around this problem, disconnect the disable_chainout port by setting parameter “Enable disable_chainout” to “No” in Native Fixed Point DSP Intel Agilex™ FPGA IP.

For Agilex™ 7 and Agilex™ 5 design developed in Quartus® Prime Pro Edition Software prior to version 24.3, you may run the risk assessment script to check if your design is impacted.

Steps to run the script:

  1. Run EDA Netlist Writer with the successfully pre-compiled design.
  2. Insert the risk assessment script in the Quartus project folder
  3. Navigate to the Quartus project folder:  cd <quartus project path> 
  4. Run the command: tclsh screening.tcl ./simulation/questa/<project_name>.vo
  5. Follow the message prompted for next step.

For deployed designs with dynamic chainout enabled in the field, contact Altera by filing IPS case (stating bug ID 15017127180) for further queries.
