3.11. IP Worksheet

The IP worksheet is an IP design entry feature that automatically fills in resource usage of commonly used IP designs , automatically allocates appropriate resources for the selected IP and calculates power consumption.

The IP worksheet is not available for MAX 10 devices.

Each row in the IP worksheet represents a separate IP domain. For the EPE spreadsheet version 11.0 and later, supported IPs are external memory interfaces (EMIs), including DDR2 and DDR3, QDR II, and RLDRAM II in different configurations (for example, x9, x18, x36, and x72).

Enter the following parameters for each IP domain:

  • Type of IP
  • Data width in bits
  • Clock frequency (in MHz)
  • Enable percentage
  • Total power in watts
