After the decoder has loaded, select Preferences from the overview screen and set the preferences to their correct value in order to decode the trace properly.

The protocol decoders, FS1136 and FS1117, require 4 parameters to be entered by the user in order to decode valid states. To access the preferences on the 169xx select Prefs from the graphic representation of the protocol decoder in the overview window. The information required is generally available from the spec. sheet of the memory device being used or by querying the BIOS of the target system.

a)Number of Chip Selects – This is either 1 or 2 based on the whether either S0 is being probed and incorporated into the IA or both S0 and S1.

b)CAS Latency – Also defined as “CL”, or the delay from a valid Read command to when the Read data is strobed on the bus.

c)Additive Latency – Defined by the chipset

d)Burst Length – Usually fixed at 4, or 8.

e)Additionally, the FS1136 has Preference selections for Data bit length and number of logic machines
