    I'm sorry, i forgot that Gray code may be better for the state encoding, please accept my corrected version and consider changing the original also to use gray code. This will reduce some of the power consumed by switching less bits.

    module wtf(clk, rst, c); output [7:0] c; reg [7:0] c; input clk; input rst; reg [1:0] s;

    always @ (posedge clk or posedge rst) begin if (rst) c[7:0] <= 8'b0; else case (s[1:0]) 2'b00 : c[7:0] <= 8'd87; // 'W' 2'b01 : c[7:0] <= 8'd84; // 'T'; 2'b11 : c[7:0] <= 8'd70; // 'F'; 2'b10 : c[7:0] <= 8'd33; // '!'; endcase end

    always @ (posedge clk or posedge rst) begin if (rst) s[1:0] <= 2'b0; else s[1:0] <= {s[0], ~s[1]}; end

    Yeah, the verb 'can' is a bit weird. And English spelling is very oddball.

    But there's an awful lot that's SIMPLE about English.

    • Few tenses (compared to some languages).
    • Only one (modern) form of 'you'.
    • The only noun-verb agreement is singular vs plural. There's no need for noun-adjective agreement.
    • No 'gender' for inanimate objects.
    • Monosyllabic words are enough for normal, everyday life
    • No one can write it correctly

    'i' before 'e', except after 'c' ...
    weird ...
    Or sounding like 'a' as in "neighbor" or "weigh". Not the most leisurely of rhymes. I think I'm going to have a seizure.

    The most accurate version of the 'i before e' saying is "i before e except where it isn't". Anything else is either going to be unrememberable or wrong.

    There are so many exceptions to this "rule", I've never been convinced how useful it is (science, eiderdown, deity, seismic, Keith, caffeine, seeing, ancient, society etc etc etc).

    While I agree with you that the rule is almost useless, some of your examples are kind of WTF themselves. The rule is only meant for situations where the i and the e make a single sound. In science, society, deity and seeing, the i and the e are part of different syllables. Also, eider is Swedish, so you can hardly expect an English grammar rule to apply.

    eider is swedish? Sure dont look like it and I cant remember seeing it. Ejder otoh is a swedish word. ;)

    That's not right either.

    I could have gone might be past tense or might be conditional. So it might have been right. I might have gone is also possibly conditional.

    "I was able to go" is right, also "I had been able to go". You have to convert the modal verb 'can' to the 'to be able to' form. You have difficulty converting modal verbs (verbs which change the 'mode' of another verb) to past tense.

    "I could go" is a perfectly valid past tense of "I can go".

    Today, I can go to the store. Three years ago, I could go to the store.

    It looks like I was wrong and that "I could go" is correct, but I've almost always heard it used in a way that implies that you are no longer able to.

    Oh, and...

    The past simple tense of "I can go" is "I could go." "I could have gone" is past perfect.

    Don't confuse syntax with semantics here. "I could go" can be interpreted as past indicative (I was able to do it yesterday, but now I can't) or second conditional (I could do it now, if i wanted to.) In both cases, the tense of the modal verb is the same.

    Obvious, isn't it?

    I think this is simply supposed to be the "set next statement" in a crude IDE that offers only variable value watching and changing...

    'i' before 'e', except after 'c' ...
    weird ...
    Or sounding like 'a' as in "neighbor" or "weigh". Not the most leisurely of rhymes. I think I'm going to have a seizure.

    The most accurate version of the 'i before e' saying is "i before e except where it isn't". Anything else is either going to be unrememberable or wrong.

    There are so many exceptions to this "rule", I've never been convinced how useful it is (science, eiderdown, deity, seismic, Keith, caffeine, seeing, ancient, society etc etc etc).

    i get your point. but i don't think i would ever spell 'seeing' as 'seieing' or would that be 'sieeing'. no wait 'siieeng'...
