I have a .xml file. It contains some registers which have the same address but different accessing type (WO, RO). They represent as alternateRegister. <spirit:alternateRegisters> <spirit:alternateRegisters> <spirit:Name>ENABLE_SET<spirit:name> I used the command below to generate RALF file. ralgen -ipxact2ralf ral.xml ralgen -l sv -t MemMap -uvm ral.ralf Howver, only one register is generated into RALF file. The alternativeRegisters could not generated. How can I do that?
