8051 Macro Assembler ASEM-51

In 1979 Intel has introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from dozens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists.

Intel had also defined an 8051 assembly language with bells and whistles for all the subtle peculiarities of the MCS-51 core, and offered a well-designed 8051 assembler, the legendary ASM51. Unfortunately, Intel obsoleted all its MCS-51 development tools in December 1993. The original (and IMHO best) 8051 assembler was gone and no longer available! ....... - W.W. Heinz,

ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is a rich subset of the Intel standard that guarantees maximum compatibility with existing 8051 assembler sources.

"In the letter, they told me that they had used my ASEM-51 V1.2 to develop the motor-control software for a little Mars car prototype..."

They had validated several 8051 assemblers, and found ASEM-51 to be the most reliable and best documented one.

Dynamic Schematic Editor - Spectrum Software

A Schematic Editor with Active Simulator oriented towards RF and Communication Circuits. Good support for Power Electronic Devices and Circuits like IGBT and Mosfet.

"The multi-page hierarchical schematic editor makes it easy to sketch a circuit. Once a circuit is created, you can do a transient, AC, DC, transfer function, sensitivity, or distortion with a simple command."

Integrated schematic editor and simulator

Micro-Cap 10 is an integrated schematic editor and mixed analog/digital simulator that provides an interactive sketch and simulate environment for electronics engineers.

Animation lets objects change their display or respond to user clicks during a simulation. In this mode, a single analysis time step is taken and the schematic displays and animate devices are updated on the schematic. The animation components can also be used in a Dynamic DC analysis.
