System Overview

We overview in this chapter the hardware modeling language and synthesis flow in Hercules and Hebe. Section 2.1 describes the modeling of hardware behavior using HardwareC [KM90a]. HaidwaieC supports constraint specification and ext ual synchronizations. Section 2.2 presents a brief overview of the ovoall synthesis flow in Hercules and Hebe. 

The mechanical system used for this evaluation consisted of several automated components feed control, reactants preparation, synchronized injected reactant pulses, reactor temperature and pressure and residence time control, on-line analytical, fraction collector for product sample collection, as well as programming for multi-system coordination. 

The intention of this section is to give a brief overview on the whole framework, since the remainder of this chapter will focus exclusively on a single aspect, namely the automatic synthesis of a behavioral specification down to the ASIC emulator board. If the emulation demonstrates that an overall performance increase will be obtained through the realization of corresponding system submodules by an ASIC, other synthesis tools (such as Cathedral or Amical, described in chapters 7 and 9) have to be used to derive a final chip solution replacing the emulator.

As a first step, the HardwareC compiler performs a profound data/control-flow analysis. A DFG optimizer is directly coupled to the compiler. After optimization, the data/control-fiow graph will be stored as a combined single flow graph which can be considered as a data base. All behavioral synthesis transformations require input from this data base and will produce output in the graph format defined in chapter 2.

The Project Scope is not maintained after the project is completed. The Outline Specification, meanwhile, must not be lost. It should be carried forward to form the basis of a System Overview that is maintained during the operational life of the computer system.

This is a single document (clear, concise, accurate, and complete) describing the purpose and function of the system. System Overviews are therefore not necessary for less complex systems where there is a single URS or Functional Specification document. 

The System Overview is a useful document to present during an inspection and should be written in nontechnical language so that it is meaningful to an inspector without the need for technical expertise. It should include ...

A brief system description covering the system s history (whether it is an entirely new system, a replacement system, or an existing system) and its business purpose is necessary. GxP regulatory authorities expect replacement systems to be as least as reliable as their predecessor manual or automatic system. The aim is to provide a management overview of the project boundaries, defining what is and what is not included within the scope of work. The system description may be supplemented later by a separate System Overview document, especially for larger systems (see Chapter 8).

Many regulatory authorities also expect a high-level diagram to be included with supporting detail as appropriate. An example system overview diagram is given in Figure 8.1.

These SOPs should clearly define the inpnts and expected outputs of the process covered in order to provide objective measnrement criteria to determine whether the process is being successfully operated or not. This state of control shonld then allow the required electronic records to be created and maintained by the system, in addition to the creation of any documentation specified as part of its reqnirements, as ontlined in the traceability requirements diagram shown in Figure 36.2. Any relevant snpporting process flows, system overview, or network diagram documentation should also be reviewed and revised as necessary to reflect the new bnsiness processes if the requirements and SOPs for the system are updated in the fnture.
