R
The VHDL and Verilog use models for instantiating a mixed usage model are provided. In
the example, a user is instantiating a non-location constrained IDELAYCTRL instance with
the RDY signal connected. This discussion is also valid when the RDY signal is ignored.
VHDL Use Model
-- Multiple instantiations of IDELAYCTRL primitives with LOC
-- constraints.
-- Each instance has its own RST and RDY signal to allow for partial
-- reconfiguration.
-- The REFCLK signal is common to all instances (LOC and replicated
-- instances)

dlyctrl_2:IDELAYCTRL

dlyctrl_n:IDELAYCTRL
-- The user should either declare the LOC constraints in the
-- VHDL design file or in the UCF file.
-- Declaring LOC constraints in the VHDL file.
attribute loc : string;
attribute loc of dlyctrl_1:label is "IDELAYCTRL_X0Y0";
attribute loc of dlyctrl_2:label is "IDELAYCTRL_X0Y1";

attribute loc of dlyctrl_n:label is "IDELAYCTRL_XnYn";
-- Declaring LOC constraints in the UCF file:
INST "dlyctrl_1" LOC=IDELAYCTRL_X0Y0;
INST "dlyctrl_2" LOC=IDELAYCTRL_X0Y1;
.
.
.
INST "dlyctrl_n" LOC=IDELAYCTRL_XnYn;
-- One instantiation of an IDELAYCTRL primitive without LOC constraint
-- RST and RDY port signals are independent from LOC-ed instances
