USBHostSlave has been successfully compiled using Quartus 4.2
For some reason I have not been able to use SOPC Builder 4.2 to build the usb SOPC component
However, SOPC Builder 4.1 generates a usable SOPC component. This may be an error on my part, I need to
investigate further.
USBHostSlave has been tested in a SystemC simulation, and on a Altera Nios development kit Cyclone edition.
Release notes:
// Version 0.6 - Feb 4th 2005. Fixed bit stuffing and de-stuffing. This version succesfully supports
// control reads and writes to USB flash dongle
// Version 0.7 - Feb 24th 2005. Added support for isochronous transfers, fixed resume, connect and disconnect
// time outs, added low speed EOP keep alive. The TX bit rate is now controlled by
// SIETransmitter, and takes account of the requirement that SOF, and PREAMBLE are always full
// speed, and TX resume is always low speed.
// Fixed read clock recovery (readUSBWireData.v) issue which was resulting
// in missing receive packets.
// Fixed broken SOF Sync mode (where transacations are synchronized with the SOF transmission)
// by adding kludged delay to softranmit. This needs to be fixed properly.
// This version has undergone limited testing
// with full speed flash dongle, low speed keyboard, and a PC in full and low speed modes.
// Version 0.8 - June 24th 2005. Added bus access to the host SOFTimer. This version has been tested
// with uClinux, and is known to work with a full speed USB flash stick.
// Moving Opencores project status from Beta to done.
// Version 1.0 - October 14th 2005. Seperated the bus clock from the usb logic clock
// Modified RX and TX fifo status registers, and removed TX fifo data count
// register. Added RESET_CORE bit to HOST_SLAVE_CONTROL_REG.
// Fixed slave mode bug which caused receive fifo to
// be filled with incoming data when the slave was
// responding with a NAK, and the data should have been discarded.
// TODO: Test isochronous mode, and low speed mode using uClinux driver
// Add frame period adjustment capability
// Add compilation flags for slave only and host only versions
// Create data bus width options beyond 8-bit
// Version 1.1 - February 23rd 2006. Fixed bug related to 'noActivityTimeOut'
// Previously the 'noActivityTimeOut' flag was repetitively pulsed whenever
// there was no detected activity on the USB data lines. This caused an infrequent
// misreporting of time out errors. 'noActivityTimeOut' is now only enabled when
// the higher level state machines are actively looking for receive packets.
// Modified USB RX data clock recovery, so that data is sampled during the middle
// of a USB bit period. Fixed a bug which could result in double sampling
// of USB RX data if clock phase adjustments were required in the middle of a
// USB packet.
