7 segment question

hi all im doing a project on vhdl and using cyclone III and part of it is to use the 7 segment display. i know how to do it the simple way but is there any component that can be used as a deco...

Hi there,

do you think of a hardware component like the 4511 CMOS IC or the 74141?

(so called BCD to 7-segment decoder)

The benefit could be, that the I/F between the FPGA and the 7-segment reduces to 4Bits rather 7Bits and the current for the 7-Segment is by the driver IC rather being an I/O current of the FPGA. (But these are all benefits that came to my mind..)

thanks man, i know the 4511 but im looking for a component within the FPGA like lpm or ff that does the same as 4511.
