Performance
Table 1
shows the required speed and estimated gate count of the
STS1FRM in an APEX 20KE device.
Note:
(1)
The numbers for the logic elements (LEs) and embedded system blocks (ESBs) are
approximate as of May 25, 2001. They reflect the range from the basic to the full
feature variant.
Generating
Variants
Table 2
shows the optional features available to generate all variants.
Note:
(1)
The numbers for the LEs and ESBs are approximate as of May 25, 2001. Users are strongly advised to run the
MegaWizard Plug-In and the Quartus II software to see exact numbers for each STS1FRM variant.
