title: The Notation Y ← A.B in ASM charts
body: <p>I am a physicist trying to get to grips with system-verilog and am trying to understand ASM charts, I think I have got to grips with them but some of the notation is a mystery to me still and I am having trouble finding the answers.</p>
  
  <p>If the following expression appears on an ASM chart "Y ← A.B"</p>
  
  <p>I gather that Y takes the value on the right hand side of the expression in the next clock cycle and keeps that value for further clock cycles (unless modified elsewhere). However I am not familiar with what "A.B" means. </p>
  
  <p>My guess is that it means A AND B (as in Y = A &amp; B, if A and B = 1 then Y = 1). Is this correct or am I missing something?</p>
