This chapter describes all functionality that is currently deprecated or legacy, and, in the former case, when it will be removed, including items removed in the current release. There are also suggestions on replacements.

7.1 Legacy in Simics 7

Functionality classified as legacy in Simics 7.

7.1.1 Product Features

Functionality	Notes
The `-echo` command line option can be used to include command invocations as part of Simics output, which can be directed to file
The script declaration system.	New code should use the target parameter framework.
The component system.	New code should use the blueprint framework.
DML 1.2	New code should use DML 1.4.
Haps	New code should use notifiers.
GNU make based module build system.	New modules should use CMake instead.
Ports and port interfaces.	New devices should use port objects.
The `[obj, "name"]` syntax for device connects.	New devices should use port objects and regular interfaces, e.g. use syntax `obj.port.name` or `obj.bank.name`.

7.1.2 CLI

Functionality	Notes
`break-io`	`bp.bank.break` is a replacement in most cases
`unbreak-io`	`bp.bank.break` and `bp.delete` are replacements in most cases
`trace-io`	`bp.bank.trace` is a replacement in most cases
`trace-io-setup`	No replacement.
`untrace-io`	`bp.bank.trace` and `bp.delete` are replacements in most cases
`wait-for-io-break`	`bp.bank.wait-for` is a replacement in most cases
`restart-simics`	It only works when running Simics locally.
The `ports` attribute (e.g. `dev.ports.HRESET.signal`).	Use port objects and the `port` or the `bank` sub-namespace (e.g. `dev.port.HRESET.iface.signal`).

7.1.3 Interfaces

Interface	Notes
`io_memory`	New code should use `transaction`

7.1.4 API

Modulo calculation in fixed sized arguments will be deprecated in Simics 7. In Simics 6, a warning will be printed when module calculation is required to fit into the type. The CLI argument types `int8_t`, `int16_t`, `int32_t`, `int64_t` `integer_t`, `sint8_t`, `sint16_t`, `sint32_t` `sint64_t`, `uint8_t`, `uint16_t`, `uint32_t` `uint64_t` will warn once if module calculation is required when calling a command.	Use only values that fit in the argument type. If required, use the `unsigned*` commands:

unsigned
unsigned8
unsigned16
unsigned32
unsigned64
