APEX 20K Programmable Logic Device Family Data Sheet
Table 22 shows the JTAG timing parameters and values for APEX 20K
devices.
f For more information, see the following documents:
Generic Testing
Each APEX 20K device is functionally tested. Complete testing of each
configurable static random access memory (SRAM) bit and all logic
functionality ensures 100% yield. AC test measurements for APEX 20K
devices are made under conditions equivalent to those shown in
Figure 32. Multiple test patterns can be used to configure devices during
all stages of the production flow.
