Yair –

First, my comments regarding Heath’s class probe only proposal apply here as well.  You are trying to define a specific optional behavior, but you are hiding the option by not calling that behavior out in the state diagram, and relying on an ‘implementation specific reset’ to jump out.  Now, you have two levels of reset (the top level diagram pse_reset, and the sism-level diagram pse_reset_pri/sec).  This should be called out as conditional arcs and an option variable rather than as a hidden option driven by a reset.  I know we disagree on that, so I won’t spend any more time on it.


Now, to the text.  There are some editorial problems that I see right away – easily fixed:

  • The text refers to alternative A and alternative B while the state diagrams refer to the primary alternative and the secondary alternative.  You should use the same nomenclature (primary and secondary) as the state diagrams.  (this is throughout the variable definitions)

Yair: Corrected. Thanks.


  • Additionally, all the references to “PSE state diagram” should be to the specific state diagram, which for most of your new stuff is a SISM diagram, not the top level PSE state diagram (145-13). For example “Primary Alternative dual-signature semi-independent PSE state diagram” for _pri signals.  This applies to the text and to the “TRUE” and “FALSE” definitions.  Yes, it’s a mouthful, but we need to be precise – especially with the many diagrams we have which interrelate, and a master pse_reset for figure 145-13 which could interrupt you straight out of the SISM diagrams.


  1. All the references to state diagram in the definition body text include already reference to the state diagram Figure which is I guess what you meant.
  2. I didnt make references to the state diagram in the TRUE and FALSE which is I believe not necessary. Look at all other parameters that we didnt do it as well.

I’ll spend some time tomorrow and see if anything in the machines is broken.

Yair: OK thanks.
