From: Jonathan David <jb_david@yahoo.com> Hm.. maybe I should indicate a willingness to do more than LURK on this list and help with the 2.3 draft, even though I won't get Scintera to join Acellera. ---Sri's last comments were: I thought they were already present in the language as bit wise operators - In chapter 4, Table 4-1 we have operators such as ~& and ~| which is bitwise and/or operators. Probably we dont have bitwise xnor. Is the same thing being referred here or something else in digital LRM that we dont have? Need to have the full array of operators in digital. Some might have some restrictions - real? ------------------------------------------- what I discovered (and mentioned to Martin a while back) was that on the digital side for reg [1:0] a; you get the following truth table for (&a) a &a |a ^a 00 0 0 0 01 0 1 1 10 0 1 1 11 1 1 0 this is the essence of a reduction operator as opposed to a bitwise operator.. the single (but multibit) argument is reduced to a single bit.. like their bitwise version, in the analog context the domain should probably be limited to integers..
