The Simulation Model page allows you to optionally generate simulation model files.
The Summary page displays a list of the types of files to be generated. The
automatically generated variation file contains wrapper code in the language you
specified earlier. On this page, you can specify additional types of files to be
generated. Choose from the AHDL Include file (<function name>.inc), VHDL
component declaration file, <function name>.cmp), Quartus II symbol file (<function
name>.bsf), Instantiation template file (<function name>.v), and Verilog HDL black box
file (<function name>_bb.v). If you select Generate netlist on the Simulation Model
page, the file for that netlist is also available. A gray checkmark indicates a file that is
automatically generated, and a red checkmark indicates generation of an optional file.
Reset ports
Create
'input_dq_sreset'
input port
— — Enables synchronous reset port that synchronously
resets all registers in the DQ input path.
Reset ports
Create
'output_dq_arese
t' input port
— — Enables asynchronous reset port that asynchronously
resets all registers in the DQ output or DQ OE path.
Reset ports
Create
'output_dq_srese
t' input port
— — Enables synchronous reset port synchronously resets all
registers in the DQ output or DQ OE path.
Reset ports
Create
'bidir_dq_areset'
input port
— — Enables asynchronous reset port that asynchronously
resets all registers in the bidirectional DQ I/O path.
Reset ports
Create
'bidir_dq_sreset'
input port
— — Enables synchronous reset port that synchronously
resets all registers in the bidirectional DQ I/O path.
Config ports
Create
'config_clk' input
port
— — Enables input clock port that feeds IO_CONFIG block
for user-driven dynamic delay chain. This input port is
used as the clock signal of the shift register block. The
maximum frequency for this clock is 30 MHz.
Config ports
Create
'config_datain'
input port
— — Enables input port that feeds the input data to the serial
load shift register in
IO_CONFIG block for user-driven
dynamic delay chain.
Config ports
Create
'config_update'
input port
— — Enables input port that feeds IO_CONFIG block update
port for user-driven dynamic delay chain.
When asserted, the serial load shift register bits feed the
parallel load register.
