Adaptive Logic Module  
Adaptive Logic Module  
Arria V devices use a 28 nm ALM as the basic building block of the logic fabric.  
The ALM, as shown in following figure, uses an 8-input fracturable look-up table (LUT) with four dedicated  
registers to help improve timing closure in register-rich designs and achieve an even higher design packing  
capability than previous generations.
