---- ----
---- YM2149 compatible sound generator. ----
---- ----
---- This file is part of the SUSKA ATARI clone project. ----
---- http://www.experiment-s.de ----
---- ----
---- Description: ----
---- Model of the ST or STE's YM2149 sound generator. ----
---- This IP core of the sound generator differs slightly from ----
---- the original. Firstly it is a synchronous design without any ----
---- latches (like assumed in the original chip). This required ----
---- the introduction of a system adequate clock. In detail this ----
---- SYS_CLK should on the one hand be fast enough to meet the ----
---- timing requirements of the system's bus cycle and should one ----
---- the other hand drive the PWM modules correctly. To meet both ----
---- a SYS_CLK of 16MHz or above is recommended. ----
---- Secondly, the original chip has an implemented DA converter. ----
---- This feature is not possible in today's FPGAs. Therefore the ----
---- converter is replaced by pulse width modulators. This solu- ----
---- tion is very simple in comparison to other approaches like ----
---- external DA converters with wave tables etc. The soltution ----
---- with the pulse width modulators is probably not as accurate ----
---- DAs with wavetables. For a detailed descrition of the hard- ----
---- ware PWM filter look at the end of the wave file, where the ----
---- pulse width modulators can be found. ----
---- For a proper operation it is required, that the wave clock ----
---- is lower than the system clock. A good choice is for example ----
---- 2MHz for the wave clock and 16MHz for the system clock. ----
---- ----
---- Main module file. ----
---- Top level file for use in systems on programmable chips. ----
