sibsim4

align expressed RNA sequences on a DNA template

The SIBsim4 project is based on sim4, which is a program designed to align an expressed DNA sequence with a genomic sequence, allowing for introns. SIBsim4 is a fairly extensive rewrite of the original code with the following goals: * speed improvement; * allow large, chromosome scale, DNA sequences to be used; * provide more detailed output about splice types; * provide more detailed output about polyA sites; * misc code cleanups and fixes.

Tcl/Tk based digital circuit editor and simulator

tkgate

Tcl/Tk based digital circuit editor and simulator

TkGate is a digital circuit editor and simulator with a Tcl/Tk based interface. TkGate includes a large number of built-in devices including basic gates, memories, ttys and modules for hierarchical design. The simulator can be controlled either interactively or through a simulation script. Memory contents can be loaded from files, and a microcode/macrocode compiler (gmac) is included to create tkgate memory files from a high-level description. The simulator supports continuous simulation, single step simulation (by clock or epoch) and breakpoints. Save files are in a Verilog-like format.
