| // 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 |
| |
| 0000000 // first two vectors have the output ignored to settle down |
| 0080000 // reset everything [1]* |
| 0080000 // keep it in reset a little longer |
| 00C0000 // clock in a 0 |
| 0080000 |
| 00C0000 // another 0 |
| 0080000 |
| 30C0000 // configured to 000 (space) |
| 3000000 // out of reset |
| 3008000 // 1 from U |
| 3008888 // 1 from all neighbors (now blocks to save energy) |
| 3000400 // 0 from D (now blocks) |
| 3080000 // reset |
| 30C0000 // clock in a 0 |
| 30A0000 |
| 00E0000 // clock in a 1 (no longer empty - N) |
