FIDES 2009 Parts Count Resistors

Dear Lambda,

The FIDES parts count methods are very nice. Having all data values in the big tables makes it very easy to use.

There are however a couple terminology inconsistencies with the parts count methods and the regular FIDES models. In order to upgrade our parts count work to the full FIDES model we need a constant mapping of part models. The FMG issue is the only one we could not assume a mapping for, but here is the list of inconsistence names that we have assumed.

Parts Count Full FIDES
Photodiode Optocoupler with photodiode
Phototransistor Optocoupler with phototransistor
Switching Power Supply Voltage Converter - AC/DC

The switch section is very confusing. As far as we could tell it is intended to be all switch types divided into two groups - resistive load and non resistive load. Then each of those groups is split into 3 lines based off of how many pins the switch has. Having the switch types and the number of pins in the same column does not make sense. Either the switch type selects the row, or the number of pins.

I realize the integrated circuit section had to be abbreviated to fit into the table, but could you check our grouping of those types

Digital integrated circuit - Digital circuit (MOS, Bipole, BiCMOS)
Memory integrated circuit - Flash, EEPROM, EPROM, SRAM, DRAM
Micro*, DSP, simple ASIC - Microprocessor, Microcontroller, DSP, Simple ASIC
Analog, Mixed, FPGA, CPLD, complex - FPGA, CPLD, FPGA Antifuse, PAL , Analog and Hybrid circuit (MOS, Bipole, BiCMOS) , Complex ASIC


Again, the parts count models are great; there were just these minor issues we came across.
