I think there are numerous reasons
1) Modelsim was the first in the market.
2) People familiar with Asic world used to use Modelsim.
3) Recent divorce of Xilinx<->Aldec caused more grief. Modelsim can be executed inside the Xilinx tools. Aldec's approach was to build a shell to run xilinx tools...
There are a number of reasons that might not work quite well. DC offset adjustment takes some time depending on time constant.
GSM uses frequency hopping TDMA (Time division Multiple Access) and narrow channels.
Here is some info about it.
200 kHz channels
8 subscribers per channel
217...
Most of the time, after DCR the signal is fed to an A/D converter. After this point it becomes an algorithm in signal processing to eliminate DC offsets.
Hi,
We are switching to HDL based design due to portability problems. However I still like the graphical representation of the top level design. For this we arecurrently using Synplify with "HDL analyst" which generates block diagrams for the synthesized design.
Our decision on switching to...
I agree with rfsystem in this one.
Let me try to rephrase a totally good explanation.
Each flip-flop is actually made of transistors.(Analog problem)
Therefore they have finite transition time. This means when they try to capture an input logic level there is a minimum voltage X which the FF...
Hi,
I've used the H8S2148 family in our embedded designs. So far what I've seen is that the hitachi devices don't use JTAG for debugging(at least the smaller devices). We are using this because of the peripherals.
Here is the dev system info
Compiler: I am using the Hitachi compiler itself...
Do you have other concerns such as security, saving dual configuration and load the latest verified code?
What is the size of the code?
The reason I am asking these questions is to find out the size of the FPGA and additional functionality you want. Do you want that RS232 port to come out? Or...
Here is a company that produces these type of motors you are looking for.

This company has appnotes that may be useful...
Here is a company that builds what you are looking for.

I would suggest sending an email to these people and checking their eval software etc.
Re: Unpack Ip ?
Soory to interject. The seemingly difficult task you are talking about issending 10/100 Mbps through E1. This is actually not quite the way it looks. In fact most of the switches do the same.
In ethernet world, the flow is controlled eeither directly or indirectly.
Direct...
Sorry... No free lunch!
chewbecca,
any digital modulation technique you will use, will use as much if not more processing power of some of the alogrithms of compression techniques.
If we dissect what you want to do into pieces we may be able to come up with something.
1) Analog signal comes...
microphonics oscillator
Hi,
I work for a wireless company. For us microphonics is defined as mechanical sensitivity of a circuit to frequencies below tens of kHz. Above this frequency generally the physical vibration is attenuated. For us, the main reason for this is, the components used in the...
snakebites,
I don't think that exact problem is easy to solve. However, there is more than one way to skin the cat. What is the real problem you are trying to solve?
