![]() ![]() You can for example change color and layer of all entities or specific entities like tex, mtext, dimensions. You can change all texts whose styles are not prefixed with "ELEC" to "ELEC Standard" style, then change all block's attributes whose tag is "DATE" to current date. You can replace all inserted blocks "DOOR-BD3" in layer "Archs" with block "DOOR-AC1", and move them to layer "ARCH-FURN" You can import and update all blocks from a standard drawing to hundreds of other drawings. With Batch Find and Replace you can find and replace text on multiple drawings. With Batch Rename Objects you can rename layers in hundreds of drawing by substituting text "Concrete" with "CONC", or add a prefix of "AC " to each layer's name Find xrefs function.JTB Batch Change brings the AutoCAD ActiveX Object Model to your command via Excel design spreadsheets. This idc code snippet does this for memory range 0圆5607000 - 0圆56070C0: auto arr, VA, xref, fnName, mem_rgn_begin, mem_rgn_end Īrr = GetArrayId( "RegionReferences123" ) Īrr = CreateArray( "RegionReferences123" ) įor( xref = DfirstB( VA ) xref != BADADDR xref = DnextB( VA, xref ) ) ![]() When the referenced addresses are present and IDA created Xrefs for these, instead of traversing all function instructions, you can traverse all addresses in the given region and save all functions that reference them. Use the "given procedure" as the call graph root.īoth solutions can be implemented in idc. The solution is same - find all fixed RAM address references and propagate them up through the call graph. Again no guaranteed method to statically get all possible functions called at a given indirect call site.įor "Another example": when the RAM address is outside your binary, no Xrefs are created. indirect function calls do not create Xrefs, thus a callgraph created from Xrefs would not be precise.when a GPIO address is accessed not through an immediate value, you have no guaranteed method to statically calculate the accessed address.Then build a call graph and propagate GPIO access info from called functions to it's callers. You can analyze all memory read\write instructions of all functions of the binary to find out if they reference a specific memory range. GPIO addresses are outside, no Xrefs are created for these. Xrefs are created between instructions and variables present in the binary. ![]() I can run ctrl-x (xrefs to) command which would list all xrefs in whole code, while I need to limit the list down to only procedures called from given top level entity. ![]() Right now the only way I can think of is to right click on each address, run "Xrefs to." dialog, produce wingraph32 chart and see top level functions that eventually refer to specific addressĪnother example: I know which RAM address holds some variable, and I want to know all sub procedures of a given procedure, where the variable is referenced. I want to see if specific top level entity ever reaches GPIOs. Memory region to which the GPIOs are mapped is known and defined. More exactly, I need to see if particular function eventually references specified memory address (or even better memory region)Ĭonsider analyzing an embedded software which is known to toggle a few GPIOs. I am aware that I may use PV for finding connection between two arbitrary procedures Are there any built-in tools for the feature I need, or should I write my own script? If so, what IDC functions might be useful? ![]()
