Titanium Dedicated Engineering provides assistance in overcoming technical obstacles.
Once a specification has been defined and authorized, several critical stages remain in every design cycle. The first stage is design entry. HDL coding is the most prominent form of entry when designing platform FPGAs. The code must be written properly for the design to pass through synthesis. Xilinx recommends that designers simulate their HDL before moving on.
The next stage is implementation, with the most important aspect being place and route. Implementation maps the HDLentered design into FPGA building blocks, creating a bitstream. Analysis is required before downloading the bitstream into an FPGA. Downloading the FPGA without this analysis can damage the device, or even the system.
Designs must also meet system timing parameters. If timing is not met after an implementation, then the code, timing constraints, implementation options, or internal logic placement must be changed. Yet adjusting any one of these areas can yield your desired results or further remove you from them.
Determining which area to adjust first can be challenging to design teams, especially those feeling the heat of a deadline. The best design teams are those that can make the necessary changes or corrections the fastest. Once the changes have been made, a final verification or timing simulation is required. If the design does not pass, more modifications are needed.
