--=====================_688299==_.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed Rather than adding a new property, Charles proposed to annotate the VPI diagrams with the vpi_handle_by_index and vpi_handle_by_multi_index functions in the following fashion: In diagram 26.6.2, under the Instance array class add: -> instance array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.5, under the Ports class add: -> port bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.6, under the Nets class add: -> net bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.6 under the Net array class, add: -> net array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.7, under the Regs class add: -> reg bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.7 under the Reg array class, add: -> reg array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.8 under the Variables class, add: -> var select vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.9 (Memory diagram) under the regarray diagram add: -> memory work vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.11 under the Named Event Array class, add: -> named event array element vpi_handle_by_index vpi_handle_by_multi_index 2. modify the vpi_handle_by_multi_index description as: CHANGE synopsis section: Obtain a handle to a sub object using an array of indexes and a parent object. TO: Obtain a handle to a sub object using an array of indices and a reference object. in the description of the argument num_index: CHANGE: number of indexes in the index array TO: number of indices in the index array In the description of argument index_array CHANGE: array of indexes. TO: array of indices In the table description, CHANGE: Handle to an object of type vpiRegBit, vpiNetBit, vpiRegWord, or vpiNetWord TO: Handle to an object CHANGE description: The VPI routine vpi_handle_by_multi_index() shall return a handle to an object based on the list of indexes and parent object passed in. The argument num_index will contain the number of indexes in the provided array index_array. The order of the indexes provided, shall be for the left most select first, progressing to the right most select last. This function can be used to access all objects whose property vpiMultiArray is TRUE. This routine shall only provide access to a bit or word of the parent object. TO: The VPI routine vpi_handle_by_multi_index() routine shall provide access to an index selected sub object of the reference handle. This routine shall return a handle to a valid Verilog object based on the list of indices provided by the argument index_array, and reference handle denoted by obj. The argument num_index shall contain the number of indices in the provided array index_array. The order of the indices provided, shall first follow the array dimension declaration from the left most range and progressing to the right ranges of the reference handle; the array indices may be optionally followed by a bit select index. If the indices provided do not lead to the construction of a legal Verilog index select expression, the routine shall return a null handle. --=====================_688299==_.ALT Content-Type: text/html; charset="us-ascii" Rather than adding a new property, Charles proposed to annotate the VPI diagrams with the vpi_handle_by_index and vpi_handle_by_multi_index functions in the following fashion: In diagram 26.6.2, under the Instance array class add: -> instance array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.5, under the Ports class add: -> port bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.6, under the Nets class add: -> net bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.6 under the Net array class, add: -> net array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.7, under the Regs class add: -> reg bit vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.7 under the Reg array class, add: -> reg array element vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.8 under the Variables class, add: -> var select vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.9 (Memory diagram) under the regarray diagram add: -> memory work vpi_handle_by_index vpi_handle_by_multi_index In diagram 26.6.11 under the Named Event Array class, add: -> named event array element vpi_handle_by_index vpi_handle_by_multi_index 2. modify the vpi_handle_by_multi_index description as: CHANGE synopsis section: Obtain a handle to a sub object using an array of indexes and a parent object.
