MyHDL: a Python-Based Hardware Description Language
MyHDL supports waveform viewing, a popular way to visualize hardware behavior. In Listing 2, the instantiation of the SPI slave module is wrapped in a call to the function traceSignals. As a side effect, signal changes are dumped to a file during simulation, in a standard format. Figure 1 shows a sample of the waveforms rendered by gtkwave, an open-source waveform viewer.
MyHDL is a practical solution with links to other HDLs. MyHDL supports co-simulation with other HDL simulators that have an interface to the operating system. A bridge must be implemented for each simulator. This has been done for the open-source Verilog simulators Icarus and cver.
In addition, an implementation-oriented subset of MyHDL code can be converted automatically into Verilog. This is done with a function called toVerilog, which is used in the same way as the traceSignals function described earlier. The resulting code can be used in a standard design flow, for example, to synthesize it automatically into an implementation.
Tim Peters, a famous Python guru, explains his love for Python with the paradoxical statement, “Python code is easy to throw away.” In the same spirit, MyHDL aims to be the hardware design tool of choice to experiment with new ideas.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
