AUTO_RESOURCE_SHARING<br />

AUTO_RESOURCE_SHARING<br />

Type<br />

Allows the Compiler to share hardware resources among many similar, but mutually<br />

exclusive, operations in your HDL source code. If you enable this option, the<br />

Compiler will merge compatible addition, subtraction, and multiplication operations.<br />

By merging operations, this may reduce the area required by your design. Because<br />

resource sharing introduces extra muxing and control logic on each shared resource, it<br />

may negatively impact the final f max of your design.<br />

Boolean<br />

Device Support<br />

This setting can be used in projects targeting any <strong>Altera</strong> device family.<br />
