public class Virtex2BitstreamParams

extends XilinxBitstreamParams

This class is used to record the information about a specific Virtex2 FPGA during the creation of an .rbentry file as well as provide a method for calculating the absolute offset of a readback state bit from the offset provided by the Xilinx logical allocation file (.ll) file. The information this class records about a specific FPGA includes the PE type, the readback bitstream header lengths, the bit ordering within each byte, the frame size, the CLB frame count, and the bitmap length. Further, this class defines constants for each supported Xilinx part type as well as each part type's frame size and count. Further, constants for the number of bits in a byte and the trailer or postamble length are also defined. Several methods are defined to conveniently calculate the length of the bitstream in bits and bytes as well as provide the lengths of frames, the number of frames, and a String representing the Xilinx FPGA type.

Constructor Detail

Virtex2BitstreamParams

public Virtex2BitstreamParams()

Constructs an object setting the value of the PE type to XILINX_UNKNOWN, the CLB Header length in bits to 0, the Block RAM header bits to 0, and the byte ordering to byteMirrored = false (in other words, bit 0 is the MSB of the byte).

Virtex2BitstreamParams

public Virtex2BitstreamParams(int idcode)

Constructs an object setting the value of the PE type, setting the CLB Header length in bits to 0, the BlockRam header bits to 0 and the byte ordering to byteMirrored = false (in other words, bit 0 is the MSB of the byte).

Parameters:

idcode - The int representing the type of the Virtex2 or Spartan3 part.

Virtex2BitstreamParams

public Virtex2BitstreamParams(java.lang.String peTypeStr,
                              int newClbHeaderBits,
                              int newRamHeaderBits,
                              boolean newByteMirrored)

Constructs an object setting the value of the PE type, the CLB Header length, the Block RAM header bits, and the byte ordering according to the parameters given.

Parameters:

peTypeStr - The String representing the type of the Virtex2 or Spartan3 part. The String should have "2Vxxxx" or "3Sxxx" in it, for example a string such as "XILINX_XC2V1000" will be recognized as a Virtex2 1000, and "XC3S15" will be recognized as a Spartan3-15.

newClbHeaderBits - The number of additional header bits for CLB readback for the platform; usually the value is 0.

newRamHeaderBits - The number of additional header bits for BlockRAM readback for the platform; usually the value is 0.

newByteMirrored - true if the LSB of a byte is addressed as bit 0, false if the MSB of a byte is addressed as bit 0.

Method Detail

setByteMirrored

public void setByteMirrored(boolean isByteMirrored)

Sets the byteMirrored field to the value of the parameter. As mentioned above, a byte array of the readback bitstream is considered byte mirrored (byteMirrored = true) if the LSB of the byte is bit 0 and the MSB is bit 7 when addressing bits in a byte. Otherwise, the bytes are not byte mirrored (byteMirrored = false), meaning bit 0 of the bytes is the MSB and bit 7 is the LSB.

Parameters:

isByteMirrored - The byteMirrored property is set to this parameter value.

isByteMirrored

public boolean isByteMirrored()

Returns the values of the byteMirrored property, discussed above.

Returns:

The value of the byteMirrored property.

setPEType

public void setPEType(int newPeType)

Sets the value of the PE type using the static final int "constants" defined earlier.

Parameters:

newPeType - The integer parameter having a value of XILINX_????? from the constants provided above.

setPETypeWithIdcode

public void setPETypeWithIdcode(int idcode)

Sets the value of the PE type using the Xilinx defined idcodes.

Parameters:

idcode - The 32-bit idcode. The upper 4 bits are ignored, since they vary between revisions of the same part & so are not useful.

setPEType

public void setPEType(java.lang.String newPeType)

Sets the value of the PE type based on a String parameter which contains "Vxxx" for a Virtex2 part and "2Sxxx" for a Spartan3 part. So, "XC2V1000" will be recognized as a Virtex2 1000, and "xilinx_xc3s200" will be recognized as a Spartan 200.

Parameters:

newPeType - The String parameter describing the part as indicated above.

getPEType

public int getPEType()

Returns the integer value representing the part type of the PE. (Not the idcode, but the Virtex2BitstreamParams internal peType number.)

Specified by:

getPEType in class XilinxBitstreamParams

Returns:

The integer value representing the Xilinx part type of the PE.

getBitstreamLength

public int getBitstreamLength()

Returns the bitstream length in terms of bits based on the declared PE type and header lengths in bits.

Specified by:

getBitstreamLength in class XilinxBitstreamParams

Returns:

The length of the bitstream in bits.

getBytestreamLength

public int getBytestreamLength()

Returns the bitstream length in terms of bytes based on the declared PE type and header lengths in bits.

Specified by:

getBytestreamLength in class XilinxBitstreamParams

Returns:

The length of the bitstream in bytes, rounded up to the next byte if the length does not end exactly on a byte boundary.

getCLBByteCount

public int getCLBByteCount()

Specified by:

getCLBByteCount in class XilinxBitstreamParams

getBRAMByteCount

public int getBRAMByteCount()

Specified by:

getBRAMByteCount in class XilinxBitstreamParams

setCLBHeaderBits

public void setCLBHeaderBits(int newCLBHeaderBits)

Sets the length of the CLB readback header (in bits) to the value of the given parameter.

Parameters:

newCLBHeaderBits - The new length of the header in bits.

getCLBHeaderBits

public int getCLBHeaderBits()

Returns the current length of the CLB readback header, in bits.

Specified by:

getCLBHeaderBits in class XilinxBitstreamParams

Returns:

The length of the CLB header in bits.

setRAMHeaderBits

public void setRAMHeaderBits(int newRAMHeaderBits)

Sets the length of the Block RAM readback header (in bits) to the value of the given parameter.

Parameters:

newRAMHeaderBits - The new length of the BlockRAM header in bits.

getRAMHeaderBits

public int getRAMHeaderBits()

Returns the current length of the BlockRAM readback header, in bits.

Specified by:

getRAMHeaderBits in class XilinxBitstreamParams

Returns:

The length of the BlockRAM header in bits.

getRAMFrameCount

public int getRAMFrameCount()

Specified by:

getRAMFrameCount in class XilinxBitstreamParams

getFrameSize

public int getFrameSize()

Maps a PE type to a CLB readback frame size based on the encodings for the part type defined in the constants above.

Specified by:

getFrameSize in class XilinxBitstreamParams

Returns:

The frame size (or length) in bits for the given part type.

getCLBFrameCount

public int getCLBFrameCount()

Maps a PE type to a CLB readback frame count based on the encodings for the part type defined in the constants above.

Specified by:

getCLBFrameCount in class XilinxBitstreamParams

Returns:

The frame count for the given part type.

getBitmapLength

public int getBitmapLength()

Maps a PE type to a bitmap length based on the encodings for the part type defined in the constants above.

Specified by:

getBitmapLength in class XilinxBitstreamParams

Returns:

The bitmap length for the given part type.

getPart

public java.lang.String getPart(int idcode)

Returns a string defining the part, based on the IDCODE.

Parameters:

idcode - The int should be an idcode as defined in XAPP139 page 7 for Virtex2 or XAPP188 page 6 for Spartan 2 devices.

Returns:

The string value of the part. They will be in the format: "XC2V4000" for a Virtex2 part, and "XC2S30" for a Spartan part. Since the idcodes are identical for Spartan2 devices >= 50 and their corresponding Virtex2 devices, this method defaults to identifying a device as a Virtex2.

getBlockRAMReadBackWordCount

public int getBlockRAMReadBackWordCount(java.lang.String part)

Returns:

A String representing the part type based on the part type encodings given above.

toString

public static java.lang.String toString(int peType)

Returns a String reflecting the Xilinx part type of the PE. Note that this is a static method. The string is in the format "XC2V4000" for Virtex2 devices and "XC2S150" for Spartan2 devices.

Parameters:

peType - The integer representing the part type.

Returns:

A String representing the part type based on the part type encodings given above.

peType

public static int peType(int idcode)

Returns the pe-type based on the idcode

whichPEType

public static int whichPEType(java.lang.String peTypeStr)

Returns an integer reflecting the Xilinx part type of the PE based on the encodings given above. The String should have "Vxxxx" or "2Sxxx" in it, for example a string such as "XILINX_XC2V4000" will be recognized as a Virtex2 800, and "XC2S15" will be recognized as a Spartan2 15.

Returns:

An int representing the part type based on the part type encodings given above. (Not the idcode, but a Virtex2BitstreamParams internal number).
