memory_map - translate multiport memories to basic cells

    memory_map [options] [selection]

This pass converts multiport memory cells as generated by the memory_collect
pass to word-wide DFFs and address decoders.

    -attr !<name>
        do not map memories that have attribute <name> set.

    -attr <name>[=<value>]
        for memories that have attribute <name> set, only map them if its value
        is a string <value> (if specified), or an integer 1 (otherwise). if this
        option is specified multiple times, map the memory if the attribute is
        to any of the values.

    -iattr
        for -attr, ignore case of <value>.
