Design Guidelines
Design Rules
Memory types, memory parts, and data widths are restricted based on the selected FPGA,
FPGA speed grade, and the design frequency. The final frequency ranges are subject to
characterization results.
For general PCB routing guidelines, see Appendix A, General Memory Routing Guidelines.
ADDR_CTL_MAP
Bank and byte lane position
information for Address byte
groups. Address requires three byte
groups and this parameters
denotes the byte groups in which
all 3 Address byte groups are
selected. See the K_MAP
description. This parameter varies
based on the pinout and should
not be changed manually in
generated design.
See the K_MAP example.
D0_MAP, D1_MAP,
D2_MAP, D3_MAP,
D4_MAP, D5_MAP,
D6_MAP, D7_MAP
Bank and byte lane position
information for the Data Write bus.
See the ADD_MAP description. This
parameter varies based on the
pinout and should not be changed
manually in generated design.
See the ADD_MAP example.
BW_MAP
Bank and byte lane position
information for the Byte Write. See
the ADD_MAP description. This
parameter varies based on the
pinout and should not be changed
manually in generated design.
See the ADD_MAP example.
Q0_MAP, Q1_MAP,
Q2_MAP, Q3_MAP,
Q4_MAP, Q5_MAP,
Q6_MAP, Q7_MAP
Bank and byte lane position
information for the Data Read bus.
See the ADD_MAP description. This
parameter varies based on the
pinout and should not be changed
manually in generated design.
See the ADD_MAP example.
