Name Register File
Symbol
Remarks A Register File contains a user-defined number of internal registers (of user-defined width), and a user-defined number of read and write port sets to access them.  On the ClockUp portion of each cycle, the two output values are the current values of the registers named by the R0# and R1# input lines.  On ClockDown, if the W control line is asserted (non-zero), the register named by the W# input is updated with the value of the WData input.

For convenience in building Mips-like machines, Register Files support "locking" of register 0. Locking sets that register to 0 and prevents it from being written. By default this option is off.
