This is the second half of the delay based Excel model tutorial. In this part the final formulas are derived and implemented in Excel 2003. The model proves to be fast and reliable and it is actually fairly easy to create. For maintaining good speed no user defined functions have been used here. Modeling Logic Gates with Delay- Part#2 by… Read More... "A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#2"
After learning how to model ideal logic gates in MS Excel 2003 it is time to attemp to create a delay based model. This first model is just a theoretical presentation about delay, how it can be explained and how it can be modeled with a minimum amount of formulas while keeping a reasonable precision. The presentation focuses on the… Read More... "A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#1"
This is the third part of a tutorial about modeling logic gates in MS Excel 2003. This first model includes no delay or loading for the gates. This section creates user defined functions for each gate and uses these functions to upgrade the model. An auxiliary macro is created which measures the speed of the model in iterations/second. The model with… Read More... "Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#3"
This is the second part of a tutorial targeted at modeling logic gates in MS Excel 2003. The first part introduced the basic logic gates,, symbols and associated logic equations. This model includes no delay or loading for the gates. The following type of gates will are described: inverter, AND, NAND, OR, NOR, XOR (exclusive or) and XNOR. The tutorial has several parts… Read More... "Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#2"
This is the first part of a tutorial (self, 2, 3) about modeling logic gates in MS Excel 2003. This first model will include no delay or loading for the gates. The following type of gates will be described: inverter, AND, NAND, OR, NOR, XOR (exclusive or) and XNOR. The tutorial will have several parts and the last part will build up… Read More...
