 Extracted warnings in #6 for SHA-1:

 %Warning-WIDTH: ../../sha1/src/rtl/sha1_w_mem.v:290: Operator ASSIGN
 expects 7 bits on the Assign RHS, but Assign RHS's CONST '6'h0' generates
 6 bits.
 %Warning-WIDTH: ../src/rtl/sha1.v:155: Bit extraction of array[19:0]
 requires 5 bit index, not 7 bits.
 %Warning-WIDTH: ../src/rtl/sha1.v:208: Operator LT expects 32 or 10 bits
 on the LHS, but LHS's VARREF 'i' generates 8 bits.
 %Warning-WIDTH: ../src/rtl/sha1.v:209: Bit extraction of array[63:0]
 requires 6 bit index, not 8 bits.
 %Warning-WIDTH: ../src/rtl/sha1.v:237: Bit extraction of array[63:0]
 requires 6 bit index, not 7 bits.
 %Warning-WIDTH: ../src/rtl/sha1.v:328: Operator EQ expects 32 or 10 bits
 on the LHS, but LHS's VARREF 'rx_ptr_new' generates 8 bits.
