Table 2–4
shows the modules that are instantiated in the
<
variation_name>_alt_mem_phy.v/.vhd file. A particular ALTMEMPHY variation
may or may not use any of the modules, depending on the memory standard that you
specify.
<variation_name>_alt_mem_phy_pll.qip
Quartus II IP file for the PLL that your ALTMEMPHY
variation uses that contains the files associated with
this megafunction.
<variation_name>_alt_mem_phy_pll_bb.v/.cmp
Black box file for the PLL used in your ALTMEMPHY
variation. Typically unused.
<variation_name>_alt_mem_phy_reconfig.qip
Quartus II IP file for the PLL reconfiguration block.
Only generated when targeting Arria GX, HardCopy II,
Stratix II, and Stratix II GX devices.
<variation_name>_alt_mem_phy_reconfig.v/.vhd
PLL reconfiguration block module. Only generated
when targeting Arria GX, HardCopy II, Stratix II, and
Stratix II GX devices.
<variation_name>_alt_mem_phy_reconfig_bb.v/cmp
Black box file for the PLL reconfiguration block. Only
generated when targeting Arria GX, HardCopy II,
Stratix II, and Stratix II GX devices.
<variation_name>_bb.v/.cmp
Black box file for your ALTMEMPHY variation,
depending whether you are using Verilog HDL or VHDL
language.
<variation_name>_ddr_pins.tcl
Contains procedures used in the
<variation_name>_pin_assignments.tcl
Contains I/O standard, drive strength, output enable
grouping, DQ/DQS grouping, and termination
assignments for your ALTMEMPHY variation. If your
top-level design pin names do not match the default
pin names or a prefixed version, edit the assignments
in this file.
<variation_name>_ddr_timing.sdc
Contains timing constraints for your ALTMEMPHY
variation.
<variation_name>_report_timing.tcl
Script that reports timing for your ALTMEMPHY
variation during compilation.
