FPGA field-programmable gate array: The speed performance of Clds chips is not fully predictable be- cause the number of antifuses traversed by a signal depends on how CAD tools allocate the wire segments during cir- cuit implementation.

Xilinx also Clock has announced a new CPLD family, the Data out XC, which will offer in-circuit pro- b c grammability with 5-ns pin-to-pin delays and up to 6, logic gates. Altera Max series architecture.

Each chip consists of a collection of SPLD- like blocks and a global routing pool to delays.
