hash tables in e :

archive

Hello everybody, i'm looking for a DB that define hash table in specman. does any such structure exists ? or perhaps i can define one using macro. i.e. definition example : tlb["signal1"] is inout simple_port of uint = "..."; tlb["signal2"] is inout simple_port of uint = "..."; tlb["signal3"] is inout simple_port of uint = "..."; usage example : tlb[signal1]$ = tlb[signal2]$ thanks,

  • For general hashing, there is a keyed list type of list that will allow you create a hash table. However, it sounds like you may have a specific requirement to connect ports or drive values to ports, which may require extra levels of indirection.

    unit xyz {
    !cs_buffer: list (key:address) of cs_data;
    write(addr: uint; data:uint) is {
    if(cs_buffer.key_exists(addr) {
    cs_buffer.key(addr).data = data;
    } else {
    var tmpentry: cs_data;
    tmpentry.address = addr;
    tmpentry.data = data;
    cs_buffer.add(tmpentry);
    }
    }
    read(addr:uint):uint is {
    var entry: cs_data = cs_buffer.key(addr);
    return entry;
    }
    }

    //Hash Element
    struct cs_data {
    address: uint;
    data: uint;
    };
