Hi, I saw there are some plans for a generalized trigger specification. http://sigrok.org/wiki/New_trigger_specification
The most general approach which would still make sense (from my point of view), are finite automata (this is an option in professional logic analyzers). The input symbol into the automaton would be a single bit or a vector. Since finite automata are equivalent to regular expressions, they could be used for syntax. It should also be possible to separate signals into groups, apply an automaton/regex to each group and then apply logic functions between groups. For example for SDRAM, a sequence on control signals (WE, CAS, RAS) AND a specific address. Regarding an implementation we would have to find or write a fast streaming regex implementation, which would tell if the current character is the last character of a matching word or not. I will look further into it in the next weeks.
