Table 1–8. Recommended Device Family and Speed Grades
Device Family
To achieve timing closure for these speed grades and variations enabling Physical Synthesis
in the Quartus II Fitter Settings is required with these options enabled: Perform physical
synthesis for combinational logic, perform register duplication, and perform register
retiming. See the Quartus II Development Software Handbook for more information on how to set
these options.
Achieving timing closure for x8 in Stratix II GX -4 will require use of the Quartus Design Space
Explorer with multiple seeds.
Multiple VCs, ECRC support, and greater than 16 tags are not recommended for x8 variations
in Stratix II GX -4.
In the -8 speed grade, the External PHY 16-bit SDR or 8-bit SDR modes are recommended
The following table shows the recommended device family speed grades
for the supported link widths and internal clock frequencies. When the
internal clock frequency is 125 MHz or 250 MHz, the recommended
setting is that the Quartus II Analysis & Synthesis Optimization
Technique be set to Speed.
See the Quartus II Development Software Handbook for more information
on how to set this.
