First, the development of simulator
Throughout nearly two decades of national development process of simulatioard chip, the scope of use is limited to domestic and 20,000 a year less than the amount the company also contributed to the Winbond After entering in 2002 announced that it would stop production of the chip.
W78958 production, the domestic manufacturers simulator in a very embarrassing situation. W78958 use at home as a result of nearly 10 years, the domestic user base is very large, these users will not be able to receive continued support, especially maintenance. In addition, the domestic focus in the W78958 on the technical work done can not be renewed and improved, many people in the industry that the industry will face a simulator to set up or re-shuffle of the situation.

HOOKS simulator technology is no doubt W78958 manufacturers after the loss of alternatives, but the absence of long-term follow-up and attention, not the short term the majority of manufacturers of complex HOOKS mature technology products. Experts believe that the overall simulator manufacturers in transition may need 2-3 years of the cycle, and there is considerable simulator manufacturers will be eliminated, the market will have mainly concentrated in a few simulator manufacturers.
Chip manufacturers as more and more resources getting stronger and stronger, with chip to chip compatible simulation simulation model, there is incomplete coverage of resources (such as additional ports, additional external interrupt), address different distribution (such as the P4 I ), to operate in different ways (such as EXTRAM, WTD) and other shortcomings. Simulation with a dedicated chip to chip or Philips simulation of more than 20 manufacturers more than 400 kinds of chips, the first simulation required more and more, so there's a new generation of simulator technology.
But a new generation of patented technology makes the simulator there is no economic power can not aff
