ISERDES VHDL and Verilog Instantiation Template
X-Ref Target - Figure 8-9
Clock Event 2
The reset pulse is deasserted on the rising edge of CLKDIV. The difference in propagation
delay between the two ISERDES causes the RST input to come out of reset on two different
CLK cycles. Without internal retiming, ISERDES1 finishes reset one CLK cycle before
ISERDES0 and both ISERDES are asynchronous.
Clock Event 3
The release of the reset signal at the RST input is retimed internally to CLKDIV. This
synchronizes ISERDES0 and ISERDES1.
Clock Event 4
The release of the reset signal at the RST input is retimed internally to CLK.
VHDL and Verilog instantiation templates are available in the Libraries Guide for all
primitives and submodules.
In VHDL, each template has a component declaration section and an architecture section.
Each part of the template should be inserted within the VHDL design file. The port map of
the architecture section should include the design signal names.
