You have implemented many designs and have solid experience in hardware development. So what could EyeKnowHow contribute to your work?

Each design is a new challenge for instance because of higher speeds or different topologies to implement. Moving forward from a DDR2 to a DDR3 memory interface will result in  many different requirements on signaling. While the DDR2 CA bus noise was clearly dominated by reflections, the DDR3 CA bus is now X-talk dominated. But overall this means that the signaling requirements are not changing as rapid as the speed increase would indicate.

Following a design guide is good ... but not always possible. Sometimes it is difficult to judge where you can deviate from a design guide without generating functional issues in your design. Other times, you have to violate the design guide to be able to implement the design at all. In this case, you might want to gain back the lost margin in other areas of your design. And of course, if you have still enough margin you can reduce cost/power or improve performance of your system when not following the design guide.
