While running the shmoo (Tegra_K1_Memory_CharacterizationV1.0.1) tool I was wondering :
Are all delays written in the result files are shown with respect to the clock (CLK_P/N) ? what is the scale ? (1 ps, 1 ns, register value ?)
Is there a way to know the maximum values tunables of each parameter ? (The purpose is to know if this tool could let us make a more permissive layout than the limits given in the Design Guide ?)
Over temperature/voltage/frequency variations, parameters will “slide” to the right hand side only or it could be to the left too ?
What value should we take in a case like the figure 27 in the shmoo app note ? +/-4 taps margin as close as 0 as possible or the value entered in the top by the tool ? (in this figure is 4 the correct value or 19).
The figure 29 seems to say to take the widest margin on both side but I’m not sure if it’s for all parameters.
