Hi

I am trying to prepare an ASMD chart for my VHDL design.

My question regarding ASMD decision boxes:

Could we have multiple conditions to be checked mentioned in single decision box?

I have seen some examples where people usually use multiple decision boxes for multiple checks.

e.g., for the following check:


Code VHDL - [expand]
1
2
3
4
5
6
7
if (A=B) AND (C=D) then
----
----
----
 
 
end if;



The recommended ASMD notation is as shown below:



ASMD AND condition.png


If I were to follow the above recommended method then how would I do the chart for an OR condition? i.e.,



Code VHDL - [expand]
1
2
3
4
5
6
7
if (A=B) OR(C=D) then
----
----
----
 
 
end if;

Hi,

I do not know how much this can help with what you want to do but basically, that is an OR function.

Thank you very much. I did not realise that 'state blocks' and 'Decision blocks' could have multiple exit and entry points respectively.

I was working on the assumption that:

State block could have one Exit point only

Decision block could have one Entry point only...
