A discussion of how Verilog vectors and arrays work.
Topics:
- concatenation operator {}
- big & little bit-ordering
- bit-ranges [n:m]
- replication operator {n{...}}
- sized integers n'n
- based integers 'bn
- $signed()
- 2's complement + and - are supported
- for loop
- type integer
- vector bit-ranges

Hi mr john, could you please upload video on spike simulator setup & usage.

If I knew how to use it myself... Maybe some day down the road?

this line : word_cnt[0 +: SEGMENT_LEN_W] where SEGMENT_LEN_W=4 , what does it mean ... ? is suspect its the same as word_cnt[0:4] ?

Yes, it is the same as word_cnt[0:4]... and I apologize for misspeaking in the recording when I referred to the big/little BIT-ordering (not to be further confused with big/little BYTE-ordering!) When you say 0:4, you are talking about little-endian *BIT* ordering because the little bit (bit 0) is on the left. Big-endian bit ordering would be 4:0 These discussions are sort-of related and might be useful: electronics.stackexchange.com/questions/622337/why-is-order-of-bits-not-getting-reversed support.xilinx.com/s/question/0D52E00006hpNT1SAM/bit-order-inconsistencies?language=en_US

@@JohnsBasementThanks , i was looking around everywhere but your video explains already a lot.
