Primitive Pin Check

The primitive pin check verifies that certain pins on certain primitives are connected to signals in the design. The following table shows which pins are tested on each NGD primitive type.

Table 5-1:Checked Primitive Pins

NGD Primitive	Pins Checked

X_MUX	SEL

X_TRI	IN, OUT, and CTL

X_FF	IN, OUT, and CLK

X_LATCH	IN, OUT, and CLK

X_IPAD	PAD

X_OPAD	PAD

X_BPAD	PAD

Note: If one of these pins is not connected to a signal, you receive a warning.
