Configuration Schemes
Table 11–10 defines the Stratix and Stratix GX timing parameters for PPA
configuration

JTAG Programming & Configuration
The JTAG has developed a specification for boundary-scan testing. This
boundary-scan test (BST) architecture offers the capability to efficiently
test components on printed circuit boards (PCBs) with tight lead spacing.
The BST architecture can test pin connections without using physical test

Notes to Table 11–10:
(1) The minimum and maximum numbers apply only if the internal oscillator is chosen as the clock source for starting
up the device. If the clock source is CLKUSR, multiply the clock period by 136 to obtain this value.
(2) This value is obtained if you do not delay configuration by extending the nstatus to low pulse width.
