    Abstract: An integrated circuit 1 comprises a timing closure monitoring circuit 2. The timing closure monitoring circuit 2 comprises a duplicate path 19, having the same characteristics as a logic path 3 being monitored. The duplicate path 19 receives a pulsed reference signal 23 from a reference generating unit (RGU) 24. The pulsed reference signal 23 is synchronized with the clock signal 13, and passed through the duplicate path 19 to a reference checking unit (RCU) 25. In a normal mode of operation in which timing closure is guaranteed, the clock signal 13 will sample the pulsed reference signal 23, such that no interrupt signal is generated on the interrupt line 33. However, in the situation where the reference check unit 25 is clocked by the clock signal 13 prior to the pulsed reference signal 23 being received via the duplicate path 19, an interrupt signal is generated on the interrupt line 33, indicating that timing closure cannot be guaranteed.

    Abstract: Apparatus and method for controlling integrated circuit operation, comprising software means for generating simulated or estimated activity, and hardware control means for monitoring real-time activity of the integrated circuit. For every clock period the hardware retrieves (at step 200) the activity estimation for the next operation. This value may be adjusted (at step 202) with an offset previously calculated which is intended to correct the estimation so as to correspond with real, monitored activity of the chip. This value (i.e. the estimation value with the offset) is used (at step 204) to control the chip (module) as it is considered to better represent the activity of the next operation. When the next operation is being executed, the activity of the chip is also measured (at step 206), and this value is then used to generate an average of the activity of all previous operations (step 208). The measured average and the estimated one are compared (at step 210) so as to determine how accurate the estimate was, and an adjusting offset may be generated (at step 212) which is the difference between the two compared values.

    Abstract: A delay circuit comprising first and second transistors (Ml, M2), the gate of each of which being coupled to the input (or "PRE") signal. The drain of the second transistor (M2) is connected to the supply voltage V D D and its source is coupling to the drain of the first transistor (M1). A third transistor (MO) is provided, the input signal (PRE) being coupled to its gate via an inverter (10). The drain of transistor (MO) is connected at a point between the source of transistor (M2) and the drain of transistor (M I), and the source of transistor (MO) is connected to ground. A capacitor (CO) is connected between the source of transistor (M1) and ground, and a buffer (20) is provided at the output (TIMER). The function of this arrangement is to propagate with delay the transitions from the PRE signal to the TIMER signal. The rising transition is propagated very fast, the speed of propagation being equal to the charging time of capacitor (CO) through the two conducting transistors (M1, M2). The falling transition, on the other hand, is propagated with a large delay as it is equal to the charging time of the capacitor through a conducting transistor (MO) and a transistor in sub-threshold (Ml).

    Abstract: The electronic circuit executes operations dependent on secret information. Power supply current dependency on the secret information is cloaked by drawing additional power supply current. A plurality of processing circuits (102, 106) executes respective parts of the operations dependent on the secret information. An activity monitor circuit (12a, b, 14), coupled to receive pairs of processing signals coming into and out of respective ones of the processing circuits, derive activity information from each pair of processing signals. The activity monitoring circuit (12a, b, 14) generates a combined activity signal indicative of a sum of power supply currents that will be consumed by the processing circuits (102, 106) dependent on the processing signals. A current drawing circuit connected to the power supply connections is controlled by the activity monitor circuit (12a, b, 14) to draw a cloaking current controlled by the combined activity signal, so that power supply current variations dependent on the secret information are cloaked in a sum of the cloaking current and current drawn by the processing circuits (102, 106).
