NAND2TETRIS HARDWARE SIMULATOR (HARDWARE DESCRIPTION LANGUAGE (HDL)) ,USING SKELETON PROGRAM PROVIDED AND USING PREDIFINED GATES ATTACHED.

CHIP HiLoMux

{

IN in[8], sel;

OUT out[4];

PARTS:

}  

Implement HiLoMux - This has one 8-bit input bus, in, and one 4-bit output bus, out. Also
present is a sel input, which is used to select what appears on out. If
sel is false, then out should contain the lower 4-bits of in (i.e. in[0],
in[1], in[2], in[3]). If sel is true, then out should contain the
upper 4-bits of in (i.e. in[4] mapped to out[0], in[5], mapped to
out[1], etc.). 

Not 4 And4 Or4 Xor4 Add4C Register8 This has one input bus, in, and one output bus, out. Each bit of the output is the inverse (i.e. not) of the corresponding input bit. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically anding together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically oring together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically Xoring together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of adding together the corresponding input bits in a and b, while making sure that any carry is propagated to the next bit. Add4 also has an additional carryIn input, which is used to feed carry into first addition, and a carryOut output which carries the carry out of the final addition. This gate has one 8-bit input bus, in, and one output bus, out, and is designed to store a single byte (8-bits) of information. As with pre-supplied Bit, a further input load controls whether the output should be updated to reflect the new input value (when true), or should preserve the output.

Mux4 Mux8 This has two input buses, a and b and one output bus, out. Also present is a sel input, which is used to select whether input a or b is passed to out. If sel is false, input a should be selected, otherwise input b should be selected. This is an 8-bit version of Mux4. It has two input buses, a and b and one output bus, out. Also present is a sel input, which is used to select whether input a or b is passed to out. If sel is false, input a should be selected, otherwise input b should be selected. Mux4Way8 This is essentially the same a the Mux8 except it can select between four different inputs (a, b, c, and d) and so sel is two bits wide - hence, 4Way... Mux8Way8 This is essentially the same as the Mux4way8 defined above, however this time there are eight inputs and sel is three bits wide. You should adapt your earlier implementation to reflect this change.
