VHDL- Overview • VHDL= VHSIC Hardware Description Language • Commissioned for US Department of Defense contracts – Initially for simulation only !
• Looks similar to programming language ADA (which is like Pascal) • Now governed by IEEE standards – 1076-1987/1993
• Popular description language for European design houses • Support from all major CAD tool vendors – Lots of different design tools available 35
VHDL - Overview • The job : – Create Hardware designs – Create Hardware designs which can be Synthesised – Create Hardware designs which can be simulated / verified » Allow for the creation of test vectors » Functional verification » Timing verification

Why/Why not Machine Code ?
• You’ve been asked to code “The Sims VIII - It’s a Jungle Out There” by Maxis. C++ or assembler, and why ?

VHDL- A First Look I • Each description comprises 2 components – Interface description- a list of the connections (ports) in and out – Architecture body- some description of how the block works A Z B
– A,B,Z are the interface – AND gate is the architecture 38
VHDL- A First Look II • So, what does the corresponding code in VHDL look like for our simple AND gate ? architecture MYARCH of ANDGATE is
entity ANDGATE is port ( A,B: in std_logic; Z: out std_logic );
begin Z 1 then output changes after some time (propagation delay)
• Synchronous – We have a notion of state – Contains gates + Flip-Flops – We have to clock the system before changes take place 43
Simple Combinatorial Architectures- I • Back to our simple AND gate example.. • Reserved VHDL keywords are in bold, lower case The architecture name (can be anything)
