Abstract: PROBLEM TO BE SOLVED: To provide a level converter for interfacing two circuits to which different power supply voltages are supplied, and an integrated circuit containing a level converter interfacing circuits in two different voltage islands.
SOLUTION: Power is supplied to a first buffer 104 with a pretense power supply V, and the first buffer 104 receives an input signal 102 from a lower voltage circuit. The first buffer 104 drives a second buffer 108 to which higher power supply voltage V
ddh is supplied. Power supply selecting mechanisms 120, 128 are so switched by an output 110 from the second buffer 108 that the higher power supply voltage V
ddh or reduced power supply voltage V is selectively passed to the first buffer 104.

Abstract: The present invention implements self testable boundary logic by using a tristate pass gate (60)and a tristate receiver (70)in combination with a linear feedback shift register (30), a storage register (120), and level sensitive scan design (LSSD) techniques. The linear feedback shift register (LFSR) shifts data into a storage register which is connected to the data inputs of the boundary logic through the tristate pass gate. The outputs of the tristate input receiver are also connected to the inputs of the boundary logic so that the boundary logic can receive data from both the data input of the integrated circuit (data path) or from the storage register connected to the LFSR. The tristate pass gate and receiver are enabled through a self test signal such that when the pass gate is enabled the receiver is not enabled and vice versa. In this way the boundary logic can only get data from either the storage register or through the receiver but not both. In this configuration data from the storage register can be input into the boundary logic without going through a multiplexer in the data path and incurring the associated delay. The boundary logic can then be self tested using ordinary LSSD techniques. This self testing can also be performed with a minimum of additional silicon area being used for the self test structures.
