Member Function Documentation

◆ addresses()

template<typename AddressT >

static std::array<AddressT, config_size_in_words> haldls::vx::SynapseDriverConfig::addresses ( coordinate_type const & synapse_driver )

static

◆ decode()

template<typename WordT >

void haldls::vx::SynapseDriverConfig::decode ( std::array< WordT, config_size_in_words > const & data )

◆ encode()

template<typename WordT >

std::array<WordT, config_size_in_words> haldls::vx::SynapseDriverConfig::encode ( ) const

◆ get_enable_address_out()

bool haldls::vx::SynapseDriverConfig::get_enable_address_out ( ) const

This enables sending the five lower bits of an address to the synapses.

The MSB is always sent. This mode must be disabled for HAGEN operation.

◆ get_enable_charge_sharing()

bool haldls::vx::SynapseDriverConfig::get_enable_charge_sharing ( ) const

Enable charge sharing for larger STP utilization values (broken).

◆ get_enable_hagen_dac()

bool haldls::vx::SynapseDriverConfig::get_enable_hagen_dac ( ) const

Enable the DAC converting a hagen activation to an STP voltage.

◆ get_enable_hagen_modulation()

bool haldls::vx::SynapseDriverConfig::get_enable_hagen_modulation ( ) const

Enable modulation of pulse width proportional to event address.

Note:

Hagen DAC must also be enabled through enable_hagen_dac
Address forwarding must be disabled through enable_address_out
STP circuit must be enabled through enable_stp

◆ get_enable_readout()

bool haldls::vx::SynapseDriverConfig::get_enable_readout ( ) const

Enable readout source follower and connect to readout line.

The readout is shared between all instances of a vertical half. Connecting multiple instances is non-destructive but will result in faulty readings. Also note that an additional buffer per half must be biased to drive the signals further down to the readout chain.

◆ get_enable_receiver()

bool haldls::vx::SynapseDriverConfig::get_enable_receiver ( ) const

Enable padi bus receiver.

◆ get_enable_recovery()

bool haldls::vx::SynapseDriverConfig::get_enable_recovery ( ) const

Enable STP recovery circuit.

◆ get_enable_renewing()

bool haldls::vx::SynapseDriverConfig::get_enable_renewing ( ) const

Enable renewing synapses for LIF sampling (broken due to faulty circuit).

◆ get_enable_stp()

bool haldls::vx::SynapseDriverConfig::get_enable_stp ( ) const

Enable STP circuit.

◆ get_hagen_dac_offset()

HagenDACOffset haldls::vx::SynapseDriverConfig::get_hagen_dac_offset ( ) const

Output voltage offset for the hagen mode DAC.

While the STP offsets also affect hagen usage, this setting allows calibration of dacen pulse timings in hagen mode across a larger range.

◆ get_offset()

Offset haldls::vx::SynapseDriverConfig::get_offset ( ) const

Calibration value for dacen pulse width.

◆ get_recovery()

Recovery haldls::vx::SynapseDriverConfig::get_recovery ( ) const

Set STP recovery time constant.

◆ get_row_address_compare_mask()

RowAddressCompareMask haldls::vx::SynapseDriverConfig::get_row_address_compare_mask ( ) const

Set row select address compare mask.

The incoming row select address allows to individually address a single synapse driver. For this purpose, the events row select address (5 bit) is compared to the synapse driver index (static). The padi bus receiver can be configured to ignore (parts of) the row select address by zeroing (parts of) the row_address_compare_mask.

◆ get_row_mode_bottom()

RowMode haldls::vx::SynapseDriverConfig::get_row_mode_bottom ( ) const

Set bottom row mode.

◆ get_row_mode_top()

RowMode haldls::vx::SynapseDriverConfig::get_row_mode_top ( ) const

Set top row mode.

◆ get_select_target_voltages()

TargetVoltages haldls::vx::SynapseDriverConfig::get_select_target_voltages ( ) const

Select a pair of STP target voltages (vrecover, vcharge).

Each synapse driver is provided with two sets of the STP target voltages, to allow for two different parameterizations within a single array. Note that although there are only two logical arrays of synapse drivers per chip, even and odd synapse drivers are fed with disjunct analog parameters provided by the east and west capmem instances, respectively.

◆ get_utilization()

Utilization haldls::vx::SynapseDriverConfig::get_utilization ( ) const

Set strength of STP utilization.

◆ operator!=()

bool haldls::vx::SynapseDriverConfig::operator!= ( SynapseDriverConfig const & other ) const
