Folders
- jt51/doc contains documentation related to JT51 and YM2151
- jt51/hdl contains all the Verilog source code to implement JT51 on FPGA or ASIC
- jt51/hdl/filter contains an interpolator to use as first stage to on-chip sigma-delta DACs
- jt51/syn contains some use case examples. It has synthesizable projects in various platforms
- jt51/syn/xilinx/contra sound board of the arcade Contra. Checkout hdl subfolder for the verilog files
Usage
All files are in jt51/hdl. The top level file is jt51.v. You need all files in the jt51/hdl folder to synthesize or simulate the design.
Alternatively you can just use the file jt51_v1.1.v at the release folder. It contains all the necessary files concatenated inside. It is generated by the script in bin/jt51_singlefile.sh
Simulation modules are added if macro: - SIMULATION is defined - JT51_NODEBUG is not defined
Use macro JT51_ONLYTIMERS in order to avoid simulating the FM signal chain but keep the timer modules working. This is useful if a CPU depends on the timer interrupts but you do not want to simulate the full FM sound (to speed up sims).

This sound core has been used at least in the following arcade cores for FPGA
- JTCPS1: CAPCOM SYSTEM arcade clone
- JTDD: Double Dragon 1 & 2 arcade clone
- JTGNG: arcade clones of pre-CPS CAPCOM games. Some use YM2151 through JT51
