FPGA Editor - How can I add an IDDR/ODDR component?


The IOLOGIC component can be configured as IOSERDES or IOLOGIC (IDDR/ODDR/ISDR/OSDR).

How can I add an IDDR/ODDR in FPGA Editor?


When you add an I(O)LOGIC component in FPGA Editor, a window appears asking you enter the component name and component type.

To configure it to I(O)LOGIC, (which means I(O)DDR/I(O)SDR), select I(O)LOGIC/I(O)LOGIC1/I(O)LOGIC2 in the type pull-down list.

To configure it to I(O)SERDES/I(O)SERDES1/I(O)SERDES2, select I(O)SERDES in the type pull-down list.

See the following examples.
  • For Virtex-4 devices, the default type is I(O)SERDES

  • For Virtex-5/Spartan-6/Virtex-6 devices, the default type is I(O)LOGIC
