Abstract
The aim of this thesis is to build a uni ed framework for synthesis and size estimation
for the LUT-based FPGA. The LUT-basd FPGA families were studied. The available
techniques of size estimation and synthesis were reviewed.In this thesis, a novel synthesis
framework is introduced for LUT-based FPGAs. This framework includes an online area
estimation engine that enables the designer to get an estimate about the size of the circuit
on the FPGA chip of the design while being described using a hardware description lan
guage. The online area estimator is built based on the available area estimation techniques.
New high level estimation models are presented and added to the estimation engine to make
it more powerful and to allow the designer to write hardware description making use of
high level constructs available in most of HDL languages. The framework includes also
a multi-engine synthesis engine that is built based on the available techniques. New cost
function for synthesis that are based on size estimation is used with a well known OBDD
bases synthesis technique. The framework has the advantage of allowing the user to input
the design in any language from VHDL, Verilog and SystemC. Besides, it o ers the designer
a language conversion utility. We gave a name to the framework ”ASU-Synthesizer 1.0”,
where the pre x ASU stands to Ain Shams University. Experimental tests were performed
to check the accuracy and the improvements obtained from this framework and its parts.
