// test vectors for basic Morphle Logic "yellow cell"
// to be used with test004ycell.v
//
// each vector in the the format of 7 hex digits
//
// for two bit wide signals 00 indicates "empty",
// "01" indicates a 0 value and "10 a 1 value
//
// the first digit is: 0,0,xhempty,xvempty
// where these are the expected values of hempty and vempty
// and these depend only on what the configuration of the cell is
//
// the second digit is: uempty,dempty,lempty,rempty
// these are 1 if the corresponding neighbors are empty
//
// the third digit is: reset,confclk,cbitin,xcbitout
// where reset is 1 to freeze the cell, and cbitin is a new
// configuration bit read on each rising edge of confclk
// the expected value of cbitout is the value of cbitin
// delayed by three clocks
//
// the fourth digit is: uin,xuout (two bits each)
// where uin is a value from the neighbor at the top and the
// expected value for uout goes to that neighbor
//
// the fifth digit is: din,xdout (two bits each)
// the sixth digit is: lin,xlout (two bits each)
// the seventh digit is: rin,xrout (two bits each)
