Getting a High Speed Synchronous N-Channel MOSFET Driver working right

[QUOTE="techn0, post: 6900967, member: 736649"] I ran a thicker wire from the regulator to the via near the gate driver and added a 10uF ceramic at that via. Nothing changed. High Gate still completely useless. Here is original PCB Top traces and bottom. I do not do schematics I just draw the PCBs. [ATTACH alt="TopSide.png"]327241[/ATTACH][ATTACH alt="BottomSide.png"]327242[/ATTACH] Mods tried from orignal PCB are 10k PWM pull down High current trace from reg out via to vcc via near gate driver 10uF cap placed right near gate driver New mosfets with better low gate on specs and of coarse resoldering and or replacing the gate driver way to many times Nothing has improved original wave forms pictured above. I have the bottom solder pad on the gate driver grounded. Should it not be? [/QUOTE]
