    Abstract: The present invention is directed to methods for verifying adequate synchronisation of signals that cross clock environments. According to one exemplary method, a circuit under design includes a plurality of functional elements and a plurality of clock environments, and has one or more signals passing from one clock environment to another therein. The method includes the steps of (i) modelling at least one of the functional elements to have an unknown state as an output for a predetermined time after a timing event of a clock signal, (ii) simulating the circuit, and (iii) determining which functional element is a synchroniser to thereby identify if there is a synchronisation problem for a signal passing from one clock environment to another.

    Abstract: A method of disassembling object code to generate the original source code is discussed, together with a lister for performing the disassembly. The object code has relocation sections associated with some of the section data. For each location in the section data the lister determines if there is an associated relocation instruction and if there is, the lister derives certain additional information concerning the section data. The lister then generates the original source code, including the additional information.One example of the additional information is an arithmetic expression used to calculate a value in a relocation instruction. The set of relocations associated with the location of the instruction are read in turn by the lister and by using an expression calculator and an expression stack, the original arithmetic expression can be reconstructed.

    Abstract: A semiconductor integrated circuit for use in direct memory access (DMA) has two sources which communicate with a bus through a bus interface. A DMA access signal generator is coupled to the bus interface and asserts a DMA access output signal at a DMA access signal pin whenever either of the sources requires a DMA access. The need for separate DMA access signal pins for each of the two sources is thereby avoided. With targets on two separate integrated circuits, a single DMA access pin can be used for the two targets, while chip select signals at chip select pins on the source integrated circuit indicate which of the two targets is intended for the DMA access.

    Abstract: An executable program is prepared from a plurality of object code modules, each object code module including section data and associated relocations and at least one of the object code modules further including code sequences at least some of which are like to be repeatedly included in the executable program. Wherever a code sequence is to be inserted, a relocation instruction specifies the location of the code sequence and the code sequence is inserted into the section data at the appropriate point. A linker, a method for assembling, and a computer program product support these operations.
