FPGA Architecture

FPGA Development Architecture

ELMG use a partition approach to product development.

This hierarchical top down approach divides the system into manageable blocks. Each block can be designed, coded and verified independently.

The partition process creates

for each block.

System Architecture

The overall hardware system is determined. From here the interfaces to the FPGA are defined to determine the I/O count requirements.

FPGA Internal Architecture

Internal architecture of the FPGA is designed. Typically this is a functional partition that minimizes the interconnections between the blocks.

FPGA Code Tree

The code tree of the partition creates a hierarchy of code modules. Each module is designed and coded. It is also tested using a module level testbench.The integration process starts at the bottom of the module tree and rises to the top.

Each integration is tested with an testbench.

FPGA Process Structure

The architecture is completed by the a process view where data flow and control flow architecture is made clear.
