Primitive: 4-Input AND Gate with Non-Inverted Inputs<br />

Supported Architectures<br />

This design element is supported in the following architectures only:<br />

• XC9500XL<br />

• CoolRunner XPLA3<br />

• CoolRunner-II<br />

Introduction<br />

About Design Elements<br />

AND functions of up to five inputs are available in any combination of inverting and non-inverting inputs. AND<br />

functions of six to nine inputs, 12 inputs, and 16 inputs are available with noninverting inputs. To make some<br />

or all inputs inverting, use external inverters. Because each input uses a CLB resource, replace functions with<br />

unused inputs with functions having the appropriate number of inputs.<br />

Design Entry Method<br />

This design element is only for use in schematics.<br />
