I wrote the assembly code for this circuit in vhdl already. I want to simulate it with a test bench. • RegWrite: 1 bit input (clock) • Write Register Number: 3-bit input(write addresses) • Write Data: 32-bit input (data in) Read • Register Number A: 3-bit input (read addresses) • Read Register Number B: 3-bit input (read adddresses) • Port A: 32-bit output (data out) • Port B: 32-bit output (data out) I think my problem is that I don't understand what this circuit does. I chose random values to assign to the inputs, but it didn't output anything. What are good inputs to choose for this circuit? In general reading an address before it is written doesn't produce any useful results. A A VHDL Implementation of a VHDL Implementation of a VHDL. Purpose CPU register file (at least 32. The thirty-two 32-bit general registers. My circuit has a grid of 32 x 8 D flip flops. Each row should be producing a 32 bit vectors that contain the Q values from the D-ff's - which are then sent to a 8x1 MUX. Feb 29, 2012 hi friends.I Have problem in executing the following 32bit register file code in VHDL. So anyone suggest me the coorections in the. I'm creating an n bit shift register. N bit shift register (Serial in Serial out) in VHDL. Up vote 4 down vote favorite. Your block diagram shows a 32 bit wide 8 word deep register file with two read ports and one write port with RegWrite used as a clock gated by the decode of the write address. A stable WriteRegNum value and a rising edge on RegWrite effects a write to the address specified by WriteRegNum. The two read ports appear completely independent. Specifying an address on the respective ReadRegNumA or ReadRegNumB should output the contents of that register to the respective output port. To get something useful out, you have to write to that location first, otherwise it will be the default value ((others => 'U'),) suspiciously like your waveform. Trying writing to a location before expecting valid read data from it. Use values that are distinguishable by register location. Theoretically you should be preserving set up and hold time on WriteRegNum with respect to the rising edge of RegWrite. From your waveform you're writing x'00000001' to register three (WriteRegNum = '011') over and over again. Change either ReadRegNumA or ReadRegNumB to '011' after the first write and that value should show up on the respective read port. The idea of a register file is to store values that may be needed for operations. A two read port register file allows two different registers to be read and their values used as operands, say as inputs to an adder. In general when not writing to a register RegWrite can remain high. Bringing it low then back high causes a write. – Mar 15 '14 at 4:41 •. I wrote the assembly code for this circuit in vhdl already.
