Power Estimation

Power dissipation in CPLDs can vary substantially depending on the system frequency, design application and output

loading. To help reduce power dissipation, each macrocell

in a XC9500XL device may be configured for low-power

mode (from the default high-performance mode). In addition, unused product-terms and macrocells are automatically deactivated by the software to further conserve power.

For a general estimate of ICC, the following equation may be

used:

ICC(mA) = MCHS(0.175*PTHS + 0.345) + MCLP(0.052*PTLP

+ 0.272) + 0.04 * MCTOG(MCHS +MCLP)* f

where:

MCHS = # macrocells in high-speed configuration

PTHS = average number of high-speed product terms

per macrocell

MCLP = # macrocells in low power configuration

PTLP = average number of low power product terms per

macrocell

f = maximum clock frequency

MCTOG = average % of flip-flops toggling per clock

(~12%)

This calculation was derived from laboratory measurements

of an XC9500XL part filled with 16-bit counters and allowing

a single output (the LSB) to be enabled. The actual ICC

value varies with the design application and should be verified during normal system operation. Figure 1 shows the

above estimation in a graphical form. For a more detailed

discussion of power consumption in this device, see Xilinx
