Global Buffers with No Programmable Delays

The CLKBUF and CLKBUF_LVPECL/LVDS macros are composite macros that include an I/O macro

driving a global buffer, hardwired together (Figure 2-20).

The CLKINT macro provides a global buffer function driven by the FPGA core.

The CLKBUF, CLKBUF_LVPECL/LVDS, and CLKINT macros are pass-through clock sources and do not

use the PLL or provide any programmable delay functionality.

Many specific CLKBUF macros support the wide variety of single-ended and differential I/O standards

supported by Fusion devices. The available CLKBUF macros are described in the IGLOO, ProASIC3,

SmartFusion and Fusion Macro Library Guide
